I can't boot XP anymore after installation, I messed up

Question: I can't boot XP anymore after installation, I messed up

Okay so I installed Windows 7 after taking a break from the Beta.

Unfortunately it didn't do what it usually does and let me boot "an older version" or anything like that. It just booted Windows 7.

I read some stuff on this forum and ended up using bcdedit to try and fix it. These are the exact commands I entered:

bcdedit /create {ntldr} /d "Windows XP"

bcdedit /set {ntldr} device partition=C:

bcdedit /set {ntldr} path \ntldr

bcdedit /displayorder {ntldr} /addlast

Note: C: Is where XP is. O: is where Win7 is.

After doing that I got a dual boot screen at start-up. When I select Windows 7 I start windows 7. When I select Windows XP it just restarts the computer and shows me the screen again.

Any suggestions? I don't know how to get back into XP now. I guess I could disable the SATA than Win7 is on and it would be forced to start up XP (which is on an IDE) but I really want to get this dual boot business fixed.

I would just say screw it and abandon XP for now except I password protected my files and now I can't get to them unless I transfer ownership one by one. :S
EDIT: I fixed my problem, and in an unexpected way. After I posted I was frantically trying to decide what was different this time (as I had gotten this setup to work before). I then remembered that I had set my SATA drive as the primary boot drive in the bios in my effort to get Windows 7 to work when the boot sector was corrupt. I changed it back to my IDE drive (the way it originally was) and the dual booting worked again.

I never would have thought that would be the problem. It doesn't explain other users who had the exact same problem though. I doubt very many people decided to play with the controllers in the bios.

Preferred Solution: I can't boot XP anymore after installation, I messed up

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

I have been messing with my windows 7 and can still get online and into cam sites and stuff but can not watch movies on my favourite Movies2k and also can not download music. This was all working fine untill I started messing and can not get it sorted. It can't be to serious but really need help please!!!!

Answer:Solved: Messed with settings, Can't download music or watch online films anymore????

1. Which settings did you mess with?

2. Do you have System Restore turned on? If so, check for a restore point prior to the day of
you changing the settings. That should fix the problem, if you have a restore point dated before the incident.

So I had a good installation, no problems, sfc was fine. Then I get the update for th2 via windows update. It downloads fine., but gets an error after the download saying to try later. So I restore from a backup and use the media creator to update windows keeping files. That appears to work fine, but when I run sfc it gets errors and cannot repair them. So I use the media creator again, and sfc gives no errors. But, here is the next problem. My disk partition layout was: recovery | 100MB system EFI | windows. After all of this it is: recovery | 100MB system EFI | windows | recovery. Now I have two recovery partitions!

So I deleted the new one with partition wizard and don't really know if that is OK.

So Microsoft, who wants to shove these updates to us, expect the typical user to cope with this? What a friggin mess.

Answer:th2 installation is so messed up

Your in Illinois and i am in NY i never even received this update yet is what makes me wonder as i received 3 runtime updates today so i know windows updates is working. Had refused to yet try it from ISO i made. If it had i can try to tell you if mine did this.

In an attempt to fix my broken pc (before we all realised it was the keyboard!), a friend decided to install XP Pro, as he thought my existing 98SE O/S was corrupt.All seemed fine, until I tried to install my copy of Nero when I was told I had to uninstall the existing Nero app. However, add/remove only saw the 2 apps I had loaded since XP. On looking in the programs folder, I was dismayed to see all the programs that were on the pc before installing XP. However - I can't access or remove them because windows doesn't see them.Do I really have to reformat etc - or can i just delete them from the registry?

Answer:XP - messed up installation - HELP!!

did you do a upgrade to xp pro or was it a clean install did you choose the ntfs file system in xp pro?if so that is why windows cannot see your previous apps as the file format is fat ,i think the only way is a reformat ,though some one else may have an idea -good luck -hol pol....

Answer:Installation Config. Messed up.

First, what do you mean by configuration is messed up? That could mean hundreds of different things.

Second, when you do a clean install, are you booting from the USB, selecting the custom install option, deleting all the partitions on the hard drive you are installing to and then installing to the blank, unallocated space?

Hey pplz.
How do i change it so that each time i enter a setup it has teh default installation path as "G:" not "C:" ??
I done it agggess ago, but forgot how

Answer:Installation to DEFUALT G: not C: anymore!

One method would be to create mutliple partitions in the Windows setup screen (after booting from the Windows XP disk) until you reach the one that would be letter G (7th partition), and install there. Another one would be install Windows as you normally would, then when you get to the desktop, go into Device Manager and change the partition name. Don't quote me on the second method as i do not know if that would work.

Hi,I really wanted to install Windows 8 after having it tested in a virtual environment. But something weird is going on.During the intial installation process, the screen is "messed up". Whenever I move the mouse, it leaves "traces" and makes the display all weird.It was really hard going through the installation process but once completed, Windows 8 refused to boot. Anyone knows why?My computer is not that old and I've looked into the minimum requirements. I don't see anything that might cause trouble. Any ideas?Specs:Processor AMD Athlon(tm) 64 X2 Dual Core Processor 5200+, 2600 Mhz, 2 Core(s), 2 Logical Processor(s)BIOS Version/Date Phoenix Technologies, LTD M2N-TVM 0203, 21/09/2006Display NVIDIA GeForce 7300 SE/7200 GS4GB of RAM1TB HDDI've also used coreinfo to see if my processor supports PAE, NX and SSE2.

Answer:Windows 8 installation Setup is messed up

In my opinion, Windows 8 is too new yet for home users to upgrade to. It's best to buy it pre-installed on a new PC or delay the upgrade for many months to give the new OS time to have several issues ironed out.Evidently there's something about your system that Windows 8 does not like.I don't think it will be very popular on the PC anyway - it was designed primarily for touch-screen technology to rival the iPad and Android tablet devices. I certainly won't be rushing to get it. Apparently, navigating around it with a traditional mouse is very "clunky". No thanks.

Hey guys, Ive really screwed up, heres whats happened.
Well, I have 2 partitions on my harddrive, I have winxp installed on 1 partition and win7 on the other, I recently encrypted my win7 partition with bitlocker using the AES 265 bit encryption. The way I got into my win7 Os was with a passkey on my usb. Now, for some completely dumb reason I accidently formatted this usb, so now I cant get into the win7 installation. I dont have the recovery key either, it really was a dumb mistake on my behalf. I can still get into my xp installation if that can help. I found a shortcut to the recovery file and it says the shortcut points to C:\, meaning the recovery file i need to get into the encrypted partition is ON the encrypted partition(I bet our laughing now)-__-. anyway, so thats the problem, when I click on the encrypted drive from winxp it says its not formatted, are there any programs that can get into the encryption so I can get this recovery file? any help would be very appreciated, coz I dont want to have to format the partition and install win7 again, thanks in advance

Answer:I messed up with bitlocker and cant get into my win7 installation

You are out of luck if you've encrypted things and then thrown away the keys.

I think this is an advanced problem. I installed a new copy of xp on a partition yesterday. I already had an installation of xp and 98se on other partitions. during installation, lists of files were scrolling up the screen for about 15 minutes. It looked like xp was indexing some hard drives. I have three 200Gb hard drives attached with about 10 partitions in total. This is because my computer gets used for video editing and other stuff.

Anyway, once xp was installed, I went to My Computer to install device drivers and stuff from one of my partitions. The list of files was correct, but i could not execute the exe files, none of them. Testing files on other partitions showed that most movie (mpg) files played mp3's from elsewhere on the same physical hardrive partition. This was true of mp3 files also. The majority of files opened other files or parts of other files. It seems to me that the way xp references file names to actual sectors or clusters got scrambled, so all the data is there but the file names don't refer to the correct data. Is there anyway to correct this? Has anyone had the same problem? Also a whole partition disappeared.

I have tried partition magic, chkdisk, pc inspector and active undelete, but none of these work.

Any help would be appreciated.
Cheers, Tony.

Hello forum.

I am literally begging you for help. Today I came home to my computer displaying a warning in message center stating my drive had errors which I had to scan. I clicked it and Windows did absolutely nothing. So I performed the scan myself.

First time, I got a message stating scan could not be run. So I tried closing it and then everything froze up, my desktop went blank and nothing responded. I had to do a hard reset and restart only to find out Windows had decided to update my machine, I thought that would be the end of my problems.

Upon Windows completing the update after numerous restarts, I was still prompted to check my disk for errors, which ended up in the scan freezing saying ''24 minutes remaining'' for over an hour. Upon trying to cancel, it just froze up and when I tried to force a restart, I noticed I could no longer use my taskbar at all, the Start Menu won't open, I cannot click the sound icon, the notification center does not respond/expand anymore. etc...

I managed to restart and Windows starting checking my drive, during the check it froze at 43% for over 40 minutes and I had to restart once again. I did SFC /SCANNOW and there were corrupted files found, but not all were fixed. These issues are also not happening in my girlfriends profile in the same computer, she does not have any issues and is able to open start menu and gets all relevant notifications and use the taskbar to its fullest.

I wanted to set up Ubuntu on my computer, and followed the instructions in the first answer to this thread: dual boot - How to install Ubuntu alongside Windows 7/8 - Ask Ubuntu

As instructed, I created a logical partition using EaseUS software. I did this on my H:/ drive, a hard disk drive (whereas Windows 7 was installed on C:, and SSD).

After a mandatory reboot for the new partition changes, I did not immediately go to install Ubuntu, although I had Live USB to do so. Instead, if I remember properly, I booted into Windows to make sure everything was OK, but only to find out that some "Windows could not boot properly", giving me the option to 'Launch Startup Repair' - which I did, but to no avail. All it did was reported that some 2 system files were missing or corrupt.

I then installed Ubuntu on a third drive because I still needed it to perform some benchmarking. I did this using the 'install alongside windows 7' option.
But now that I don't need Ubuntu anymore, all I am interested in is getting back to Windows, while keeping all the files and programs intact.

How should I go about fixing this? Delete the logical partition on the other drive? I also have that Windows installation CD, and I'm thinking its repair options could be useful - but not having a whole lot of self-confidence, I don't know what steps exactly to take to preserve my files.

Any help is greatly appreciated!

After updating BIOS, I've enabled UEFI + Secure Mode, saved the changes and... couldn't start the PC anymore. When turning the PC on, monitor immediately goes into power saving mode, there is obviously no signal coming from the PC. Removed the Nvidia Quadro NVS 300 and plugged the monitor into board's VGA slot, no success. Tried to clear the CMOS (battery out, jumpers), nothing helped.

So I was doing a clean install of Windows on my Lenovo x250. It has a 16gb SSD M.2 "Cache" drive and a standard 500gb main drive.

Unfortunately I selected the M2 drive as the installation path and formatted the other drive. So I have Windows on the smaller SSD which is now the "C" drive.

What I'd like to do is make the larger drive the C drive, install windows on that drive, and then use the smaller SSD as the cache drive like before.

I have tried diskpart and the Admin tools in the Control panel to attempt to change the drive letter on the C: drive, but it keeps giving me an error ("The Parameter is incorrect"), regardless of what drive letter I try.

I'm wondering if I simply can't change the C: drive this way, and what other options I have?

Answer:Lenovo X250 - Messed up windows installation onto M2 Cache Drive

Okay, so have tried multiple things to no avail. Looks like the issue is that there are two drives on the system and the Windows installer just doesn't like this. Resolution is typically to remove all other drives other than the one you want to install on. However, in this case the SSD M2 drive removal would require me literally taking apart the system, and for some unknown reason there is no ability to disable the drive in the BIOS (thanks for that Lenovo!).

Any other options anyone can think of?

Hi, I am running Windows 7 SP1, 64-Bit on a Lenovo T500 with switchable graphics. I downloaded and installed Service Pack 1 manually (working on the Intel-card) since it did not show up on Windows Update (now I now that this was because of outdated Intel-drivers) - the installation went fine. Afterwards I tried to switch to my Ati-card but nothing happened and I realized that the Intel-driver has apparently been updatesd by SP1 (had a new design of the Intel-tool). After playing around I now got my Ati-card active but I can't switch back to the Intel-card. I uninstalled all graphic drivers and removed all graphic devices from the device manager and then installed the most recent driver from Lenovo and also tried with the most recent driver from Ati/AMD directly (11.2) but nothing solved my problem. I can  right-click on my PowerManager-battery and select the other card on "Switchable graphics" but nothing happens - no error message but also no change.  Every help is much appreciated.  CheersDominik

Okay, so I'm not sure whether this should go under a Windows or a Linux section, but I figured it's more Windows-related so I'm posting it here.I was trying to partition a hard drive in Windows XP's disk management, until I realised that XP's built in tool does not let you resize partitions. I have two hard disks, a GB master and 160GB slave, and Windows is installed on the 160GB. I accidentally right clicked the 160GB in disk management and clicked "make active partition" (there was no confirmation when I clicked it, it just did it immediately). I also defragmented the hard drives.Upon the next boot, I found that it wouldn't start - it said "NTLDR is missing, press CTRL+ALT+DEL to restart). Oddly enough, I inserted the XP installation disk, and when it said "press any key to boot from CD..." I did not press any keys, and I let the "boot from CD" time-out. When it did, it booted into Windows perfectly!I thought this was just a random error, so I didn't think much of it. I decided to install Linux (VectorLinux 7 SOHO) onto the 40GB partition, and it installed the GRUB boot loader (boot loader that is used by Linux). However, when I restarted to try the new OS, I still received the "NTLDR is missing" error.I popped the XP installation disk back into the CD drive, ignored the prompt, and lo and behold, the GRUB boot loader appeared and allowed me to boot into Linux!

On a T43 I have for the kids, they often get viruses which I usually clean up for them. But one seems to have messed up the BIOS. I made sure my IDE disk is first in the boot order and I even moved the network to Disabled. But each time it goes to the Broadcomm adapter to boot up and of course the result is "Operating System not found".  I am able to force a boot from a CD and from that point access the disk, but my wild guess is that the virus has renamed the network adapter as the hard disk or something like that.  Does anyone have any advice of how to repair this problem?  TIA!!

I am studying for my A+ certification and I wanted to try to install Recovery Console on my PC. I set the CMOS boot order to first boot from the CD ROM drive. I put my XP Professional installation CD in and restarted the computer. Once the XP setup program started running it looked like it was copying files, which scared me because I thought it would ask me before it did anything. So then eventually it got to a menu screen and I decided to press F3 and quit the setup, without installing Recovery Console. I went back into CMOS and reset the boot order to boot from the hard disk drive again, then saved and exited. However now it won't let me boot into Windows anymore, but rather prompts me to insert a bootable floppy or CD-ROM, which is obviously not what I want. I think I may have erased or copied over Boot.ini, and possibly other files. I want to go back to my previous settings before any of this occurred, and I need to keep all of my previous data, settings, programs, etc... in other words I don't want anything erased or changed at all. I'm hoping somebody can provide me step-by-step instructions on how to do this. I would greatly appreciate any help. I am using Microsoft Windows XP Professional SP3. I built the PC myself, it is not a store bought PC.

Hi there,

Another challenge for the experts ! Without going into too much detail, by moving hard disks around etc. I managed to screw up my 8.1 boot settings.
Partition-wise I should be ok as the 350mb "system" partition is still there, containing all necessary files.
System will however go straight for automatic repair and tell me it was not able to repair the problem.
bootrec /scanos returns 0. Bcd file seems fine when I take it through bcdedit. Renaming the bcd file and trying to rebuild one doesn't work either as it says there's no installation found.

I did not touch any partitions nor files btw, everything is still there and in tact as far as I know.

Okay, so let me first tell you that I am in a state of panic. I have very important data on my HDD and am unable to boot any OS on it now.

I initially had Vista and 7 on it, working, until I decided to uninstall 7 for XP. I deleted the partition 7 was on (C; my primary partition) and installed XP onto it. That went smoothly and all, but after booting it up I noticed it wouldn't let me specify which OS I wanted to start; it would just auto start XP. I went into the bootup settings in XP and changed the time operating systems are displayed from one second, to ten, yet it still just auto-booted XP. I was able to access the data on the other partition in the XP explorer, but seemingly wasn't able to boot from it. So I "backed up" all my data onto a third partition I had created as a failsafe in case something went wrong and I couldn't boot either of my OSes.

It then came to my attention that I had installed Windows XP Professional instead of home edition, so I made a bootable CD with the XP iso and restarted the computer for reinstallation. According to the program, the setup files copied over fine and all, but when it auto-restarted to continue the installation process it would just loop on and off at the BIOS screen. After trying 4 different versions of XP to no avail, I stuck my Vista Home Premium disk in and booted from it.

My pc specs * asus z97-p motherboard * intel i7 4790 cpu * bequiet 630w psu * 8gig corsair vengeance ram * samsung 850evo 250gig ssd (win 7pro 64bit drive) * sandisk ultra II ssd 128gig ssd (win 10 drive) * 2x crucial 500gig bx100 ssd (data drives)

i recently rebuilt this into a new case and it had been working fine. Mainly using the win 7 os but more recently using the win 10 os more and more. The way it has been working is that win7 is the default boot and I have to hit the delete key on startup to select win10 to boot from.

today I was on win 10 but needed to reboot to 7. Upon doing so I hit this message:

Secure Boot Violation The system found unauthorized changes on the firmware, operating system or UEFI drivers.

It then gave me the option to boot to win10 as it is the next boot option on the list. Win 10 is now giving me the blue screen "memory management error" although I have been able to get into win10 after some more rebooting.

I ran SFC scanner and it told me that there were some problems that it cannot fix.

Everything is unplugged apart from mouse, keyboard hdmi to screen and ethernet cable. Unplugging the win10 drive from the mobo and switching the win7 drive to another port has not helped.

Has my ssd failed? has win 10 done an update that has caused this problem? It did update today, in fact the first error message I got was after win10 shut down, and when I booted into it again it installed some updates before launching.
thanks for any help!

Answer:dual boot win7/win10 wont boot to win7 anymore +BSOD "memory managemen

Hi @vinvanda.

As far as I can understand from your post that you had W7 and W10 as dual boot in two different disks.

From the uploaded data we could not find a hint of the BSOD that you said (it is not recorded anywhere, probably because it happened during boot); but some other statements are supported by the data.

Windows failed fast startup with error status 0xC00000D4.

Now, it is STATUS_NOT_SAME_DEVICE; reads as .... "The destination file of a rename request is located on a different device than the source of the rename request".

Now I am making a guess. It it is wrong, please rectify and state the proper situation.
You name the Windows 7 Disk as "system" and the Windows 10 disk as "Win 10". You also said that windows 7 is the default boot. So I am guessing that the boot files are in the the windows 7 disk.

The board is set as Legacy BIOS. So Fast Boot is not possible here; and if Fast Startup is enabled, windows7 needs to disk check in every startup. It is desirable to keep fast startup disabled on a computer with W7.

Now Coming to the "Secure Boot Violation". Windows 7 does not support it at all. And, it is the Firmware Validation Process of UEFI; whereas your system is set to Legacy. I think here lies the issue.

BIOS Mode Legacy

Disable UEFI and Secure boot> Hopefully Windows 7 will boot back.

If it does not, remove the windows 10 disk... Read more

Question: Messed up my boot

So yay!
My computer gives me the cool NTLDR error.

Short story long:
Comp came with vista.
Created a partition, slapped xp on it.
Dual boot xp and vista.
Win7 beta comes along.
Created a partition, slapped Win7 on it.
Yay triple boot xp, vista, and win7.
Win7 official comes along.
Deleted vista partition, deleted old win7 partition.
Merged the two together.
Slapped win7 on the partition.
Win7's setup creates some random 100mb partition?
Boo, only single boot win7?
Ran some program that rewrites the boot to dual boot xp/win7 (I knew what I was getting into)
Yay NTLDR error!

So I'm currently using the NTLDR utility to boot into xp (in fact, the only way I could get into xp).

Is there any way to unbrick my boot so that I could dual boot xp and win7 without reinstalling/formatting/messing with xp's patition (I don't care about win7 ATM)?

Question: Messed up Boot.ini

Just built a new box and wanted to move my SATA hard drives to the new box and keep my XP installation intact. Usually I do the repair installation through XP setup and have no problems, but was having trouble with that. I read somewhere that initiating a XP Upgrade on the old box and continuing it on the new box should make the process easier (not true). So I initiated the upgrade and when rebooting, turned machine off and moved hardware over to new box. Had some issues with the new box that were unrelated but was finally able to boot. Now the problem I had was I had two entries in the boot menu when booting from my C: drive. One was Windows XP Pro and the other was Windows XP Pro Setup. When I chose the setup, to try to continue the upgrade installation, it freezes. When trying to do a repair installation (not recovery console), it does not detect my previous Windows installation. In any case, I was able to boot into XP using the fix_hdc in UBCD4win. I should have just stopped there, but I wanted to get rid of the Windows XP Setup load identifier, so I went ahead and tried to rebuild Boot.ini. That did not remove the Windows XP setup entry, but now I can't boot into XP because I keep getting the error that HAL.dll is missing or corrupt. Tried replacing HAL.dll with the dll on the disk, but was still getting that error. Did some research and the HAL.DLL error is due to a corrupt Boot.ini.

* Ran out of space on my 840 Pro and purchased a 500gb Samsung 850 EVO which had plenty of space and I successfully migrated over to the new drive a couple weeks ago.

* I've been using Acronis 2015 for backups and an external 4tb WD drive for these backups.

* Today I went to backup the NEW boot drive and saw I had a very large backup for the old boot SSD. In Acronis you have to boot to their program straight out of BIOS to access and erase the old backups, which I did.

* NOW I can't boot to the new Samsung 500gb drive for some reason. I've gone into BIOS and changed boot order to the 500GB but I just get a blinking cursor and a black screen when I reboot.

* However, if I change the boot order in BIOS to the OLD SSD it boots fine AND recognizes the 500gb and all it's data! What am I doing wrong?

My Sat Pro M10 worked fine until yesterday. I removed the harddrive just to check Part number (as i need to install a larger drive and want to make sure I got it right)and then re-inserted it. Now it boots up as far as the XP Pro loading screen (black background) which disappears and then the screen goes blank. This is what normally happens during boot-up, except that there would be a cursor over the blank background for a few seconds until my desktop appears. Also, when it has stopped at this blank screen the harddrive light on the front of the laptop flashes regularly every few seconds. I desperately need some of the data on the hard-drive (and no, it is not all backed up) so I do not want to use the recovery CD which is just a ghost image (isn't it). The drive is formatted as NTFS. I mention this because when I tried to use the recovery disc to check disc integrity it gave an error message that said the NTFS logfile is not loaded. It will not respond to any of the F8 safemode-type options. I think I have messed up the booting up process somehow by removing the drive rather than physically breaking anything. it seems it can read the boot partition but no further. Can anyone suggest how to fix this, or worst comes to worst a way of retrieving the data from the disc?

Thanks and appreciation in advance,

Answer:Sat Pro M10 will not boot up anymore

Hi Chris

If the system runs stabile you can remove HDD so many times you want and it should have no any influence on anything. I have removed HDD from my Tecra very often and it still works well.

Back to your issue: if there is any possibility try to connect your HDD as external device to other notebook or desktop to see if you can see it and even back up all your important data.

All Toshiba notebooks, I suppose, since two years have NTFS and that is nothing unusual.

I cannot turn on my PC. When I turn on the power supply it does a repeating, fast, high pitched, but quiet beeping sound (similar to some bird chirping). The power button on my PC doesn't respond at all, even the fans won't start. I tried disconnecting pretty much everything from my motherboard and adding more and more things slowly to no avail. I also tried out a new PSU but the same thing happens. If I disconnect the 24 pin cable, only then do I get a different sound (a continous high pitched sound). Before this I accidently plugged in the old PSU's FDD cable into one of the F_USB slots. Could I have killed my mobo with that? If not what could be the problem? How can I sort out if it's a bad mobo or something else?

I just built a new computer about 2 months ago or so. It has run fine up until this point, It started with BSOD's but reinstalling windows fixed that and I have had 0 problems since.

This morning I turned on my computer, and all it showed was a black screen. no intiial beep before loading windows like it usually does. I restart the computer and this time i get the beep, but it just sits on the menu where it shows the stats of my computer hardware (also the menu where I enter bios). It freezes at this point and theres nothing I can do, I try entering bios, nothing. Restart computer, exact same problem. I gave it an hour or so and went back, and now i'm at the origional problem. I turn it on and it just sits there, without loading video, without beeping, and without the possibilty to get into bios.

It was running perfectly fine the night before, I didnt install anything new, or mess with any hardware. Any ideas?

Answer:Ssd won't boot anymore

WELL, you didn't say what SSD you have. BAD!
But, it sounds like you had the same experience that I had a few months back, when my three month old PNY SSD decided one day that it didn't want to work anymore. I called PNY, from whom I bought the drive, but they would not do anything without the original invoice. So I was stuck, with a worthless piece of crap that I could do nothing with.
I got right on my backup drive, pulled up and ordered a new "SanDisk, 128GB, SSD" and requested two day delivery.

Now it's several months later and my SanDisk SSD is still working like a champ. It came with the SanDisk Dashboard, which includes the "Trim" program to keep the SSD in top shape.

Sounds like you need a new SSD. I strongly recommend a "SanDisk" SSD.

Good Luck, and Happy Holidays!

So, my box was acting a little fragile lately - Stuff falling off my desk onto it would make it blue screen and load back up.
Naturally I opened it up and looked inside and found one of my RAM was a bit loose - It was in there most  the way, but out just enough so that the prong that holds it in wasn't in the slot for it. I pushed it in and secured it properly, screwed the cover back on, plugged everything in.
and now it won't get passed the DELL boot up screen. F2/F12 do nothing, and the loading bar freezes about a half way in. I'm running vista(naturally), all my peripherials are USB, but I don't think its the keyboard just not working that's causing the problem. I'm tried booting it with everything plugged in, and nothing plugged in.

of F1 or F2.
F8 wont boot to safe mode either.
Is there any way to get this to boot in safe mode or from a disc so we
can repair or get some data off?


Answer:can't boot anymore

The CD-ROM needs to configured in the BIOS boot order to be first in the list. It may already be so in your machine since your recovery disk would have to boot that way.

If you can do that, you can try creating a bootable CD with the recovery console on it per my suggestion in post 6 here:

The beep when you startup and the prompt for f1 or f2 may indicate a misconfigured BIOS -- you might look for an option to reload the BIOS/Setup defaults there, and see if that particular problem is resolved. It is different from the missing or damaged "system" hive.

Hi everyone

I need some serious help here

The story is a little long
3 weeks ago, I had my computer working, and suddenly, it stopped booting windows, not even the logo show on screen, also no error code or anything. I couldn't enter diagnostic or safe mode (just bios). I had to format and reinstall windows 8 because any restore options worked.

Then a week ago, again it stopped booting, no error code, no anything, but this time, it bothered me that just 2 weeks before happened the same, so I started checking everything, so I took my Hard Drive, and put it in another computer, and it worked with no problem, windows booted, just not in my computer.

I started to look for solutions, and one was to use the command bootrec /scanos, and i got suprised that no windows installation was found. Eventually I had to speak with Microsoft tech, and they said it was my components because they were old, and they actually are (8 years), but I wasn't convinced that was it.

Before getting Windows 8 Pro, I had installed Windows 8 release preview, and it worked for months with no problem.

I thought that of course the fulll version would be heavier for my pc, so I installed Windows 7 again (had it installed for years before w8 release preview).

I decided to boot Windows 8.1 off a flashdrive so I would have my own computer basically.Iv been booting off the flashdrive for about 3 days. I created it with Wintousb. Today I installed some programs on the flashdrive and messed up Windows 8. I can boot normally into windows 8 and login and everyuthing but i ca not save ton the desktop and Word,Google Earth,steam,and adobe will not run they all get errors. Word says Can n ot create temp system variable. I can than keep clicking through the errors and eventually use it but when i try to save i get more errors. I googled around and fixed some things with regedit but it didnt help. I also tried to go to the user folder from C:/users/zfamily(Our user) but i get permission denied please ask your administartor for permission. I beliove if i can regain permission to that folder all the problems will be fixed because most errors occur somewere in that folder. Is there anyway i can fix this with being an admin or asking my dad to help? Any suggestions are greatly appreciated. Im pretty good at computer stuff. So if its complicated i can probaly figure it out.

Answer:Windows 8 Messed up after Usb boot

System Restore to before this happened should fix it.

That does require Administrator access though.

I had posted this on another forum:


Well, long story short, I installed Ubuntu and then wanted to uninstall it. Read that I needed to use EasyBCD to restore my boot config and I messed up by choosing the wrong partition (not drive, partition). So now my computer won't boot up and I get the error:

Windows failed to start. A recent hardware or software change might b the cause. To fix the problem:

1. Insert your Windows....
2. Choose your language....
3. Click....

If you do not have the disc.....

File: \Boot\BCD
Status: 0xc000000f
Info: An error occurred while attempting to read the boot configuration data.
I have he recovery disc on a USB and tried following this guide:
Recovering the Windows Bootloader from the DVD - EasyBCD - NeoSmart Technologies Wiki

Every time I get to "attrib -h -s C:\boot\BCD", it says he file can't be found. I'm pretty sure my boot drive is C. So right now I don't know what to do. I really don't want to lose my data, so I'm hoping that I don't have to format. This is a Sony Vaio laptop, so I may end up bringing it to the Sony store tomorrow to see what they can do.

Question: Boot screen messed

My "ulstata.sys" driver got corrupted and had to completely rebuild the boot options.
On doing that I am now back to the original SP2 Boot Screen and am not able to change it back to my custom image via TuneUp Utilities.

I'm kind of guessing one of the "winload.exe.mui" file isn't allowing the change.
"C:\Windows\System32\Boot\en-US" has only "winresume.exe.mui"
"C:\Windows\System32\en-US" has both?

Can you please help me, I've tried copying the loadfile in System32/en-US but it's not letting me paste in the System32/Boot/en-US due to some folder protectioin. although i've taken full control.

Tuneup Utilities is ssaying it's applied the boot screen but vista is still loading the SP2 boot screen.

Admittedly this machine is long in the tooth, and I will be getting a new one. Problem is I want to get it running again, at least to access my files. This old 700Mhz Athlon ran XP Pro well enough with 512mb ram. The 17Gig drive was getting pretty full but after removing some programs it had 900mb free I think. The problems started with the usual internet security things: growing problems with popup ads, possible viruses, a variety of malware and then IE being constantly redirected. I've used several malware removal programs which helped some but not entirely. Things got very slow and sluggish, and then all sorts of error messages that were often different each time. More and more time trying to eradicate these problems had less and less effect. Then in booting up it would take forever, probably loading all sorts of unneeded processes as seen in Task Manager, running worse each time over a period of several months. At last it was unable to finish booting up at all, just starting over after a 10 or 15 minute bootup attempt.

I am now reading a 1200 page book on XP looking for answers, and just getting more confused as it tends to raise more questions than it answers. Trying to boot up in Safe Mode gets few results. Doing this produced a DOS listing of driver files, but this appeared to stop in the middle. But still the drive was running (about 5 minutes), then up comes the black Safe Mode screen with an hourglass cursor. I eventually did ^-alt-del to get Task Manager to ... Read more

Long story short, my XP/7 dual boot is no longer working due to the fact that whenever I reboot, 7 automatically loads instead of giving me the option to choose XP or 7. I loaded up EasyBCD 2.0, and I found that the XP boot entry was absent for some reason. Without spending time trying to find out why it was like this all of a sudden, I tried adding the boot entry back. EasyBCD said it detected the XP drive and automatically made an boot entry, so I re-installed the Vista/7 bootloader, saved, and rebooted.

What happened? 7 automatically booted up again. So I went back into EasyBCD, and the XP boot entry was gone again. Quite frankly, I'm at a complete loss. Has anyone else had this issue before?

Answer:Dual boot got messed up somehow

I suspect your problem is that you reinstalled the 7 boot loader. Create a new entry for XP, but don't do anything else.

Google EasyBCD. It will allow for you to dual boot between Vista and XP. Just make sure you have the boot.ini info from you XP boot ready so you can add it to the Vista boot manager.

Long story short.

Win XP SP3 installed on a SATA drive.
Went to install Vista on the secondary drive, that is IDE.

Since it was on 2 different drives, i figured no problems, the boot loader would show earlier version of windows, and windows vista.

Nope. Only showed Vista. Got into Vista, used VistaBootPRO and for some reason unimaginable, didn't read what i was doing this time, figured i had the right selection figured out. I choose to go with deleting the current boot loader and to go back to the old style boot loader [option in vistabootpro].

Well the only thing i didnt notice here is that Vista wasn't noticing the old copy of XP either. So i reset the computer, and having both drives still in the PC, it gets past the initial loading screen, then just takes me to ...

Boot.ini not found

and then even that just goes away, and nothing happens. Computer is done doing anything.

I open up the side of er' (lucile, by the way) and just unplug the IDE drive. well at least my SATA drive loads up XP no questions ask, and nice and smooth.

Have been yet to find any method of being able to remove and repair the fact that my extra drive thinks it should load from it first. Thats all i want to do!

In vista, I was using EasyBCD, and I didnt like how long it waited before booting into the default OS, XP. So I changed the timeout to 3 seconds. Since then, Ive really found no need for Vista. But now that I want to use it, when my computer boots, I dont even get the option of choosing XP or Vista for those three seconds. Ive tried mashing the UP & DOWN arrow keys as it boots to try and get it to stop, but it doesnt help. Ive also tried installing EasyBCD in xp, but it just continually tells me that there is no Vista bootloader installed, would you like to install one, installed successfully, please restart the program. When you restart the program, you get the same set of dialog boxes.

Here's the deal. I have a custom PC that runs Windows 7 Ultimate 64 bit and it has worked fine since I built it a year or so ago.

The other day, I reformatted my mom's hard drive for her. It is a SATA II HDD, I connected it to my motherboard, booted to the Windows XP Pro 32 bit disc, reformatted her hard drive, and installed Windows XP Pro 32 bit on it.

After removing her hard drive from my computer, my system is no longer useable. Windows 7 will not boot at all. Insterting my Windows 7 disc and trying to repair the install does not work at all, the disc shows my Windows 7 installation but if I try to repair it it simply says it's the wrong version for the disc, which is absolutely false.

How on God's earth do I fix what I have done? I am ready to dump this thing forever and buy a laptop.

Answer:Windows 7 will not boot anymore

Your mistake was to allow the XP install to see your Win 7 as it booted up for the first time. At that point the system was seeing two drives both with the Active flag set and has probably written an XP style MBR to your Win 7 disk and XP was using that to get started. When you put the XP disk in another computer it almost certainly won't boot either.

The damage is only to the MBR and possibly the PBR and should be repairable but you need access to an expert to carry it out. Bit beyond my abilities I'm afraid.

I recently left my PC in my flat for the summer and when I came back to it 7 weeks later to turn it on Windows XP wouldn't boot up.

I turned on the PC and the Windows XP Home loading screen came up but it was all funny colours and then after that screen where it usually asks me for my password the screen just went black except for some strange lines of colours across the screen. At first I thought it was the monitor but I have since tried that on someone else's PC. The PC will now occasionally boot up in Safe Mode but that only happens once every 10 trys or so and when it does it still has the strange colour scheme all over the monitor. I have no idea what could possibly be wrong whether it be a loose connection in the machine or something. Any sort of help on whats wrong will be greatly appreciated.

Answer:Windows will not boot up anymore.

Well, if it's not the monitor, it's probably the graphics.

i have been working at this for a week and i was finally referred to you guys by a friend of mine. my problem started about 2 weeks ago. i had turned my computer off for the night and the next morning i went to turn it on again and it took about half an hour to boot (no joke). i started it in safe mode and it froze up after it loaded crcdisk.sys so what ever comes next is the problem but i don't know what comes next. i first though it could be a hard ware problem but i changed out almost all the parts and it still won't work. i tried to reinstall vista because this was becoming annoying having to turn on the comp 30 mins before you need it but, the vista disk isn't damaged but it still didn't work, so it must be a driver or something like that. i put in my motherboard disk to install the drivers and it didn't work and i reset my CMOS and that didn't work either. it will get through the whole install and again get to crcdisk.sys and then crap out any help you have for me would be great i have pretty much been defeated on this one. thanks - Matt

Hi - I have Dual Boot on Leopard / Vista

I have not had trouble going between OS' but for some reason Vista has taken to starting with a Black screen (similar to the F8 screen)

Windows failed to start. A hardware or software change might be the cause.

To fix problem
1. Insert win install disc
2. Choose Lang
3. Choose repair.
Safe Mode
Command Prompt (advanced)
Start normally

Windonws will start in 30 secs..

After countdown it starts with the Loading graphic.... and then suddenly flashes up with a message I can't catch as it's too fast but I see a flash of the dreaded blue screen, Rebooting itself back to the Black screen.

I put the Vista Disk in and let the computer reboot but no change - fortunately holdong down Option allows the OS selection screen to appear.. this includes the Vista DVD in the drive.

If I select Vista the computer it would just keep on rebooting over and
I have a Seagate External Drive that was my Auto Backup drive... If I had to delete the Windows partition and redo Bootcamp, would that backup be any use?? Never had to do a repair like this.

Any suggestions????

Answer:Vista won't boot anymore.

Seems like you have a vista bootloader problem. Run your Vista DVD, after selecting language settings hit r to enter system recovery options. Click Startup Repair and go through the wizard. This should help with your boot problem!

I've only found one reference to my problem and that was on this site in the wrong forum. I haven't found any answers, though.
My IBM 600 laptop has decided it doesn't want to boot anymore.
Instead I get an error 127 message after it tests the memory and reports the 228800KB's OK.
In testing the components from the dialog box that opens I get an "DEV 001", "ERR 42", "FRU 1110" message when testing the systemboard and testing the memory causes the machine to freeze up. Everything else tests OK.
The situation is the same regardless of whether I use the onboard battery or the AC adapter. It's the same regardless of whether I use the HD or my emergency boot floppy.
I've replaced the CMOS battery and reset the date and time.
The machine is identified as type 2645-45U, serial number 78-KNR91 05/99
The platform once booted is Win98SE.
The bios is IBET39WW and the CPU is a Pentium II at 300mHz
The motherboard is model number FC/01/00
I'm going to keep poking at the problem but I'd sure appreciate it if someone could give me a leg up on what to look for.
Thanks in advance.

Answer:IBM 600 127 error, won't boot anymore

This is nearly always a sofware error, meaning requested procedure cannot be found or is caused by very big file tables The size of the data file is actually the main culprit.
But you can see it in a PC when the hard drive becomes defective, or memory goes awry.
This is a serious error requiring some real work. Test your memory and hard drive in an enclosure or another machine.
If the hard drive is older than two years, consider replacing the drive and rescuing the data from the old drive in a USB enclosure.
But since you have already tried everything, you can learn from the Thinkpad forums that old 600, 600E, (not so much 600X) boards fail, and give this error as they do... or the cpu fails... check the fan on your cpu to be sure it is able to cool.

HP laptop ZE4310 - 7 years old - XP SP3

Although CD-ROM is on top of the boot devices in the BIOS the CD ROM is systematically ignored when I want to boot a bootable CD. This was no problem in the past.
At boot time the drive is accessed (LED shows short activity) but that's all before switching to the HDD (the original 30GB disk was replaced in the past with a 120GB without apparent problem - maybe the boot problem stems from this ?).
The drive is seen allright under "My Computer" and I can play audio and DVD disks but although Autoplay is marked, that does not work either.

Opening up the laptop to find the CMOS battery to reset the BIOS is a no go because I don't want to vandalize the machine. It's not simple to take it apart.

I would like to reinstall XP but without recognizing the CDs it's difficult. I do have an external USB CD ROM drive. Any known trick to boot from this device ?

Thank you for your valuable input.

Hi all,

I have a Dell 8100 PC running Windows XP Pro/Sp2 with a internal IDE Benq CD-RW drive as the 2nd device on the cable. The 1st device is a Pioneer DVD-RW writer.

I can read CDs okay from the CD-RW drive but all of a sudden I can NOT use the CD-RW drive to boot up system! Last time I tried was probably 3-4 months ago.

I go to boot menu as system is starting to boot up and select IDE CD-ROM Device -- system Beeps twice then it says:
"Strike F1 to retry boot, F2 for setup utility". I hit F1 -- same thing!

Drive is listed as okay in device manager.

I have double checked devices in BIOS, all is okay. Even set CD drive as first boot device there, but after saving setup and rebooting - system still boots from HDD with a bootable CD in drive! Even tried a Ubuntu live CD and same thing happens.

Hi people

I have a tecra A4 and started experiencing start-up problems after shutdown. the laptop would take 15 minutes to allow me to restart it if i was starting it straight after i shut it down. when i press the button to start it up it would take 2-3 seconds then just shut down with the hard-drive making a little 'clunking' noise as it did it.

I ran a recovery disk which just screwed it up all together, it just simply would not start at all after that! (just kept shutting off after 2-3 seconds). Sooooo I went out and bought a new HD. I put the hard-drive in and started installing windows again. it got to the part of putting the files into the installation directory. i think it got to 100% but then shut off again. now it wont start-up again!!! It does the 2-3 second thing :-( The difference is that there isn't the 'clunking' noise anymore. just a quiet shut-off as though its losing power somehow before it accesses the hard-drive

Any idea what the problem is here?

Answer:Can't boot into XP anymore after installed W7

You installed XP and then Windows 7 into the same partition?In this case it is to be expected that XP is inaccessible since it no longer exists. Two operating systems cannot share a partition.Files encrypted with one installation of Windows will be inaccessible with another, even if the user name and password are the same. Unless you took the proper precautions, such as backing up the encryption certificate, these files will be unrecoverable except by advanced and very time consuming methods.The best way to dual boot XP and Win 7 is to install XP first and create a separate partition for Windows 7 and install it there.

Then things got worse. Now I have to boot in safe mode, or else my computer shows... Nevermind, for further information look in the thread and ask me if you need explanation. Please, hurry, I will have no computer for a day starting in a few hours cuz i'm going somewhere and I really want to show my friend something in my computer that I can't show him in safe mode.

I've been up all night trying to fix this..

So I have been having issues with installing WOW and AOC due to memory issues, I was getting blue screens that said

so I downloaded memtest and prime95 to diagnostic the problem, will it reported back that memory slot 1 had 410 errors, but I was having problems isolating if the it was a bad slot or bad stick. So I ran prime95 torture test and during the test I received a bluescreen and it came up and went away so fast I couldn't notice the error so I had to reboot.When the computer came back up it started going extremely slow, so I decided to reboot into safe mode. It took roughly like 10 mins to just see the windows logo then another 10-15 mins to get to log in screen then another 10 mins to type my password then another 20 mins to see my desktop and this was all done in Safemode.

So now I rebooted again, this time I would get black screen for like 30 mins after Windows logo. So I decided to just re-install Vista it took a very long time to get to Vista re-install screen and next think you know it I get blue screen with the following error

nvstor.sys address 863e9395 base at 863e50000 DATAMAP 46671a61

So then I figured it was dvd drive I was install from so I unplug the defective drive and used my 2nd dvd and run install again, this time I managed to install Vista took roughly 3 hours, and now BINGO re-i... Read more

I have windows 7 operating system installed in my notebook. But suddenly my notebook is not booting anymore. I do have a backup image saved in a external hard drive, but can not install windows from there.
How can I re install windows 7 as I do not have a backup DVD.

Can anyone help me out?

Answer:Windows 7 does not boot anymore

Hi, The save image backup on the external hdd won't help you. You have to options now:

1 order a recovery disk
2 Get Win copy disk and make a custom installation. All Toshiba drivers are available

Btw, what about hdd image (F8)? Maybe , you can restore the factory settings with F8 on startup........

After clocking my CPU from 8X to 12X in the BIOS setting, my computer would not boot up anymore. It does not beep or run a POST (power on self test).

Note: It is a 8-bit KT7 RAID Motherboard and 800mhz Duran processor.

How can I reset the BIOS setting??

Thanks in advance,

Answer:Computer will not boot up anymore

Hold the insert key down while you power up, it sets abit's to default processor, then go in the bios and reset the processor speed.

In other words, hold down the insert key, push the power button on, and keep holding the key until you start to boot.

Hello everyone

I recently ordered a new cpu fan (which I have replaced since bearings shot in old one and making lots of noise), for a AMD Athlon (K7) Socket A processor and now the new fan runs quietly but pc will not boot (the mobo is K7 Triton series GA-7VKMP). If I put the old fan back on windows boots no problem. I put the new fan back on and PC hangs and won't let windows boot. It hangs before it starts looking for boot order.
It says that system health is ok and processor ok but it hangs an will not boot to windows. If I try to get into BIOS nothing happens it still just hangs.
The new fan is A.M.B. Model FD06010 Ball Bearing DC 12volts .28Amps.

Anyone have any ideas.
Thanks for any help with this issue.


Answer:replace cpu fan but pc won't boot anymore

sounds like the fan is not supported by your motherboard. You can try getting a Molex power adapter converter and plugging the power of the fan into the adapter and using one of the Molex connectors on the PSU. However, your motherboard Bios might report that the fan is not connected. I would find a CPU fan from your motherboards site that is compatible.

Hey =)

My screen randomly froze yesterday (stayed locked, couldn't move mouse or anything) and now W7 is stuck at "Starting Windows". The little icons won't appear and it stays stuck there for hours.

In safe-mode it gets stuck at CLASSPNP.SYS and locks.

Trying to reinstall doesn't work, it just reloops. I tried with another HDD, with new RAM, with another Video-Card, reset CMOS, nothing works.

Surprisingly, I can boot up Ubuntu just fine atm, no problem whatsoever.

I had this same issue when I had Windows Vista....anyone able to figure out what's happening?

Answer:Can't boot or Install anymore.

Press F8 until you can see the option to see safe mode with command prompt, then type rstrui.exe

Hi Guys. I really need your help.
I have 3 drives. Vista installed on primary boot drive (C. Everything used to work fine until I installed XP on my second bootdrive (D.

In fact, when the XP installation finished and the system was booting up for the first time, it really creeped me out with some weird non-standard characters on the post screen. For a sec I felt my BIOS is messed up or something...

It didn't even let me boot into XP until I set D: as my priority1 boot device. XP now boots fine (although it feels like it's taking a lot longer than usual) but when I switched priority1 boot device to C: my system hangs at the "Verifying DMI Pool Data" message.

I then booted back into XP and tried different tools like VistaBootPRO and EasyBCD to fix my boot files but nothing works. I can still read files from my all drives whilst booted into D: (XP) so thankfully my C: is not dead but if anyone has any experience in this area, I would very much appreciate your help.

What I want is to have some boot option at system startup to boot into either Vista or XP, simple (or not so simple) as that.

Answer:Help! I can't boot into Vista anymore!!

I cannot run windows anymore, it won't boot. I also am not able to Boot from CD at ALL. At first I was, so I booted the CD but when I realized I had to do a new install (wipe my hardrive) I decided to try startup repair first. It went on for 3 hours so I assumed it wasn't going to work so I restarted the computer. Now when I turn on the computer windows doesn't even load, it just freezes on a black screen after the Starting windows screen comes up. When I try to boot from CD (I even set boot priority to CD first) It will tell me Windows is loading files, and once that's done the Starting Windows Screen appears and it just freezes on that. I have no idea what to do. Please help.
EDIT: Also just to note, a while back I got a USB flash drive, and spent an hour putting it in the front two USB ports, and eventually they broke (the metal inside) So my computer always gives me a USB over current error) And ever since that I have a common problem (tends to happen when I hold the power button to shut off the computer) where once the Dell screen comes up, (the one that says press F2 and F12 to boot menu and setup) it just freezes there, and the only way for me to get past it is if I turn off my power strip that the computer is connected to and back on.)
Also, after constantly turning off the computer trying to fix this problem, I get a Disskete seek 0 drive) error ontop of the usb over current error whenever I try to boot from CD)

Answer:Windows will not boot anymore

I think you have a hardware issue; probably multiple problems. I will move your thread to the Hardware forum, but my guess is that your computer will need hands-on repairs. Good luck.

If you get to where you can boot Windows, or at least the installation DVD, this can be moved back to the Windows 7 forum. Just click on Report and make the request.

My PC:

Manufacturer: Acer
Intel Core Quad Q6600
320 GB HDD (2x 135)
Nvidia GeForce 8500

My PC is 3.5 years old and had it shares of little problems like every PC, yesterday I got a BSoD, along the lines of "PAGE FAULT IN NON PAGED AREA". Had quite a few number of BSoD's before but usually I quickly found out the reason for them. Or some which I never found a reason for, but didn't not have any immediate effect on the computer.

However, this time when rebooting it would get to the screen where you can "start windows like normal", or some sort or Problem Fix. Which ever option you would choose it would loop (usually with a restart) back to that screen, sometimes also changing the language from my native language to English. I attempted to boot in safe mode, but this would not boot at all and more or less go back to the same options. Eventually the computer would be going to a screen suggesting to use the repair disc (Because windows could not be started) saying:

File: \Windows\system32\Winload.exe or various other files, for example at the moment it is a file called uliahci.sys
Status: 0xc0000221 (with the uliahchi.sys)
Info: Can not load windows because an essential file is damaged or missing.

I am currently stuck on this screen and I've tried various things, will list them below. Sometimes there will also be another screen popping up:
"The file header checksum does not match the computed checksum"

Answer:Vista, won't boot anymore.

Start by checking the hard drive for errors. You can use chkdsk or download one of the diagnostic tools from the maker of your hard drive.

Well, I now have an unbootable computer. I don't know what's wrong. When it tries to boot, it gets a BSOD, and it goes by too fast for me to possibly read it. I heard you can change this option by getting into a special menu with F8, but F8 doesn't do anything for me. I heave the option of loading Startup Repair, too, but its SLOOOOOOOOOOOOW! There's no way this can be right! (Maybe I need to put the harddrive on an eternal reader and grab the dumps.)

Prior to this, the OS was laggy. I was playing music with Winamp, and it k.....ept pausing. Prior to that, I had a mess where all the programs became unresponsive and I had to force a reboot. Now, this may be unrelated, but prior to all of this, I had not one but two harddrives start to fail. One of them did fail. Now, I'm being good as far as I know. I have a surge protector on this stuff. Is there a surge coming from within? Is it time for a new motherboard, and is that the only thing that will save me? Am I smarter than I look, or not?

I'm on a budget. I really don't want to have to replace everything if I can avoid it.

I'm running WIndows 7 on a Gigabyte H55M.

Answer:Solved: Can't boot up anymore.

Hi. Although I jumped in on this thread I felt afterwards that it maybe better to start a new thread with this issue.

From about 3 wks ago when swiching on my laptop I find now that I am unable to get past f10. While on the f10 options I have tried the HDD Self-tests both short (2mins) and the long ones(37mins) and they both passed, not to sure in what that means. My laptop is a HP compaq nx9105, running winXP Pro. At the moment I have no clue in what is going on but really feel that the issue could point to a failing harddrive, although both "Self-tests" passed. If anyone has more knowledge of this particular issue more than me I would appreciate that very much, before spending out on a new hard-drive, i.e a particular CD, recovery, boot, diagnostic or other that may help.

At two stages after switching back on I did manage to get past the "a disk error has occured" and got to the "Checking file system on C: The type of file system is NTFS" to in the middle of checking or so "an unspecified error has occured", if that is a clue to anything. Also after switch-on I find that I can sometimes get the "start windows normally" DOS pop-up and then the windows XP logo, but continually loops between the two, if that helps. Thanks for your time and best regards

Hi all !

I used to create USB boots using the Program Ultra Iso and boot and install windows with my USB flash.

but this time it isn t possible.

when i choose to boot from USB, a black page comes, giving the message :

start booting from usb device ...

but it remains on this page and nothing further happens.

I tried the same flash on another system and it booted completely.
it shows that the USB is written correctly and it must be something wrong with my system.

Thanks for your help !

Hey everyone,

I've got this problem that's driving me mad and I can't seem to figure it out.

I have an Intel P4 3.0ghz on a Intel D865GLC motherboard.
It's about a year and half old and a couple of weeks ago I started noticing problems with booting and it seemed to be power related.

It won't start up anymore. The green light inside goes on, so it does have power, then when I push the power button, there are 2 ways it responds. 1) Either the green powerlight goes on and stays on and the cpu fan wil rotate once or twice and then stops, it won't do anything else. 2) nothing happens at all, not even the green light goes on. It alternates between these two situations.

It seems like it gets a short boost of power and then stops.
I had the power supply checked and it was fine and I just replaced the fan and the power cable as well, so that's not it. The processor seems fine, no bend pins or burns.

This is really frustrating me and I would really appreciate it if anyone has any input. I could bring it in, but these people charge 70 bucks just to look at the thing.

Answer:Computer won't boot anymore

Sounds like a power or heating issue; you might have damaged something

An old rig had a similar problem, and it was a faulty power supply. Though you say yours is fine . So idk
