Question: I installed the Ubuntu Operating system on my computer by mistake

I installed the Ubuntu Operating system on my computer by mistake. Foolish. But that's what happened.I thought I was installing the Ubuntu that is used for storage purposes.When I tried to restart my computer it would not restart.I inserted the "Repair disc Windows 7 Ultimate 64-bit" and eventually I got my computer to startup.So I am still able to use my computer normally.But my computer now seems to be totally corrupted because all drives are labeled incorrectly and Data1 and Data2 are completely missing. I know this is true because I saw the above info while using the Repair disc Windows 7 Ultimate 64-bit.It seems that I am stuck with a corrupt computer.What are my options?Is my only option to reinstall windows 7?Or do a backup from an Acronis image file? What can I do?Moderator Edit: Moved topic from Virus, Trojan, Spyware, and Malware Removal Logs to the more appropriate forumRoger

Preferred Solution: I installed the Ubuntu Operating system on my computer by mistake

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.)

Answer: I installed the Ubuntu Operating system on my computer by mistake

try using sfc /f

if that fails then wat i would try next is a repair install.

Run a repair install of windows 7 from a windows 7 cd. just make sure it is the same version.

I installed the Ubuntu Operating system on my computer by mistake.

Foolish. But that's what happened.

I thought I was installing the Ubuntu that is used for storage purposes.

When I tried to restart my computer it would not restart.
I inserted the "Repair disc Windows 7 Ultimate 64-bit" and eventually I got my computer to startup.

So I am still able to use my computer normally.

But my computer now seems to be totally corrupted because all drives are labeled incorrectly and Data1 and Data2 are completely missing.
This is what the Windows 7 Repair disc showed when I ran it.

The Repair disc labeled the Operating System that it finally found as "Recovered". But it was a corrupt Operating System.

But I am able see and browse all my drives and files whenever I turn on my computer.
How can that be?
The Windows 7 Repair disc says everything is corrupt.
But my computer looks perfectly normal when I turn it on.
Is my computer corrupt or not?

I tried to create an image backup of my computer using Acronis.
It gave me the below error message:
Backup failed. No reason given as to why.

Anyway I tried to fix the corruption by trying:

I tried using sfc /f
It didn't find any problems.

I ran a repair install of windows 7 from a windows 7 cd.
It didn't find any problems.

I tried to do a system restore to an earlier point in time.
None of the system restore options worked. All failed to restore to an earlier point in time.

Answer:I installed the Ubuntu Operating system on my computer by mistake.

Do you have everything backed up? If so, you could do a clean install which should get you back to the day you bought it. Do this as a last resort if no one else comes along to help out.

Hi-I bought a used Dell Optiplex 780 with no o/s installed to replace my old Dell Dimension 3000.  I have a brand new copy of Windows 7 to install on it.  I've reinstalled xp on my old computer 2 or 3 times so I'm not completely new to this but, I thought I'd try to find out as much as possible before I begin.  Any advice will be appreciated.  I am wondering - when I connect the keyboard, mouse and monitor to the Optiplex with no o/s, will it recognize the components so that I can begin the installation of Windows 7?

Hi all. My pc would not boot up. I used my XP install disc and tried all the repair options. As I was worried I might lose everything I took the pc to a computer shop and he said he would have a look but that I might have to do a full re-install.
I came back and he had wiped the drive and installed Windows 7 32 bit (I had previously been running XP).
I was gutted but he said that was my only option.
I've since seen tools advertised for repairing such issues, i wish i had been able to try these.
I have since tried a couple of free recovery tools to try and rescue some valuable documents, but they don?t find anything.
A) have I been badly advised ?
B) is there any way I can recover some of my old documents ?
I am very sad :(

Answer:PC would not boot - computer shop installed new operating system - have i lost everything ?

What free tools have you so far tried? Someone here 'might' be able to offer further advice.
Though I fear you have probably lost most, if not all, of your stuff. I guess a costly lesson re: Backups, has be learned!

Sorry if this has been asked before...My regular WinXp Sp2 system is runing on disk C which has just one partition. I have a spare drive (M) that I currently use for backups. Assuming that I can get a copy of Ubuntu, can I install it to this other drive (without impacting my WinXp system of course)and then have the option of booting up from either? Sounds straightforward, but I'd like your opinions first before I risk destroying my perfectly good system just so that I can see what Ubuntu looks like.Thanks.

So, my old hard drive on my M91p Tower was failing, and I was unable to boot into Windows 7 Professional. I replaced the hard drive, reinstalled Windows 7 Professional. It authenticates, all was good, I was happy. Then I left it installing software overnight. I woke up, it was 'asleep'. Wouldn't wake. Had to turn it off, and then when I restarted, I got the intel black screen 'OS Not Found' screen. Finally, I managed to insert the installation disc, shut down without installing by declining to reinstall it, and when I booted back up it started normally. My question is: What's going on? How do I fix this?  I didn't have Lenovo media to reinstall from, and used a Windows 7 ISO disk install. How do I fix this?  My last week have been a gauntlet of trying to fix errors. I really want to put to rest the issue so I can go on with my work regularly. What can I do?

Answer:HDD died. installed a new one, installed OS. Now it give black screen "Operating System Not Found

It is hard to diagnose without seeing it.  You left it reinstalling software..  It is possible that some installation failed and left the machine in a state where it needed to be completely powered off.  It is possible it is a hardware error in the M91p.  As I said, it is hard to diagnose without seeing it.

that ever since he tried to install something (that didn't open an application, leading me to believe that this was a trojan), my internet has slowed down

tremendously. Also, I've noticed some generally weirdness (sometimes th computer becomes really, really slow. Ping is ok, but websites say page can't be


So I booted my Kaspersky Internet Security Suite 2010 and did a full scan. It was able to detect some trojans, and then delete them... but it didn't seem to

I have new HP laptop, which had Ubuntu installed already. decided to install Windows 8.1 64, which I had on DVD. While starting installation I choose "Internal CD/DVD ROM Drive (UEFI)" (don't know what is UEFI) and I deleted all partitions and created new ones, after that installation gone well. But when I start my computer, two OS Boot Manager appears - Ubuntu and Windows, also when I opened "This PC" there was only one Local Disk C, on which I installed Windows. So I decided to reinstall windows and hoped for better and when I installed it and after choosing Windows Boot Manager another screen loaded, "Choose Operating System" and there was two Windows 8.1 (on Volume 3) and Windows 8.1 (this restarts laptop), also there was only one partition again. default boot loader is Ubuntu's and GNU GRUB appears every time I start my laptop (if I don't press ESC). What I need is to delete everything ubuntu, windows, another windows and install new windows from fresh.
Here are screenshots:
This GNU GRUB loads when I start laptop and when I choose ubuntu boot.

Windows 8.1 on Volume 3 works.

My ThinkPad A21m (2628-F2U, PIII 750 MHz (256KB), 512 MB RAM) works very efficiently with Windows 2000 SP4 and seems to work better on the internet with dial-up, than my higher-powered, 2GB RAM Windows XP computers). Unfortunately, it is now difficult to get anti-virus and firewall software that are compatible with Windows 2000. (I suspect - but haven't had the chance to fully investigate it yet - that my A21m would not meet the hardware specifications for the current versions of anti-virus and firewall software anyway. I was wondering whether switching to Linux, Ubuntu, or some other operating system would help or would only add to my woes. If I switched to Linux, for example, would the Thinkpad drivers and software work with the new operating system? Would most other programs, such as Outlook Express, Microsoft Office, and so on, work with the new operating system? If anyone has had experience with the problem of Windows 2000 no longer being supported by anti-virus and firewall providers, I would appreciate your suggestions and comments. Thank you.

Answer:Operating System for A21m (2628-F2U) - Linux? Ubuntu?

I had the same problem with my A21m (2628 - GXU PIII 800 MHz) a few years ago, so I upgraded it to Windows XP Professional (SP3). My machine is also fully loaded with 512 MB of RAM,  I then installed Norton as the anti-virus/firewall software. I have to admit that the machine is rather sluggish though. I tend not to use it in favour of my 3GB R500.

I can barely download programs because it involves the web browser and always goes to the D drive. Is there any way i can transfer my things from the D drive back to the C drive. My c drive has like 69GM free space.

if i reinstall, is there a possibility that it will install to C drive. if so can you guide me? I have an Sp2 operating system CD, but the problem was when i tried to use same cd and cd key, it rejected it so i got an sp3 cd and it was able to install, but then it installed to the wrong drive, D. I really wanted everything to install to drive C as my primary drive

Answer:When I installed SP3 it installed my operating system to D drive

You need to make backup of all your documents, data etc. before you think of re-installing.

Then put XP Cd in and boot computer off it.
Do not choose to repair existing XP installations but do a clean install.
When the screen comes to choose a partition, choose the first partition. Later choose to format the the selected partition using NTFS.

Now you will have a clean install of XP with C: drive as root drive

I plan on dual booting Ubuntu along my Windows 7 system. The only thing I am concerned with is how would I go about making a system image of Windows 7 and restoring it if I have to...with Ubuntu already installed? Would I have to wipe my hard drive of both OS and reinstall Windows 7 with my back up image or is there ways to install the windows 7 image without affecting Ubuntu or both?

Answer:How does system image of Windows installed along ubuntu work?

Ubuntu has the buzz but from personal experience I'd recommend Madriva One 2011 esp. if you have broadband internet connected via a network card.

Easus image backup free:

Best free data backup software. Hard drive backup and recovery freeware. Hard Disk image freeware.

with this program and an external drive you can back up the entire HD or particular partitions.

What I would do:

Burn the Boot CD for Easus ToDo. Make sure your system will boot from it and you can see your HD and external drive before doing anything else. If the restore on the Boot CD can't see the drives try a different program. Another is Macrium Reflect Free:

In case of disaster you have to be able to restore the image using the Boot CD.
The image back up tool is only as good as the Boot CD with the restore. If you can't see it, you can't restore it.

Use the Back up entire disk option before you start altering partitions. Be able to get back to square one if anything happens.

Then once you have Windows and Linux peacefully coexisting and booting correctly, use the back up option to make an image of the individual partitions. If Linux breaks, just restore the Linux partition. If Windows, just the Windows etc..

Both Easus and Macrium are very easy to use. There are others also.

I installed a Windows XP Home Edition SP2 in my Windows XP Professional Edition. When my computer restarted I saw that I have 2 operating systems. I realized my mistake, so I did a system restore on Windows XP Pro. I had set it before I installed Win XP Home. When I restarted again, it then boot in Windows XP Pro.

While I was using the computer, it gave a warning that I was low of space. So I had my disk clean up. Then I did the Disk Defragmenter, it said I only had 14% of space and it wont be able to defragment because it needs at least 15%.

Answer:Operating system not installed

Aisha_Zahir Hello;Allow me to welcome you to the HP forums!Wish I had good news for you, but I don't ... According to the HP product page for your laptop, it came preinstalled either with Windows 7 or Windows 8 -- which is NOT good news for updating to Win10. The older version of Win10 (10586) that came out last November tended to fair better with the older PCs than the current version (14393) that came out this August. So, if you attempting the Update from the current version, that could explain why it failed. My desktop has been running Win10 without problems since the earliest days of the Insider Preview over a year ago and it's sailed through Update after Update without problems.  So, you can imagine my surprise when the latest Upgrade  trashed my PC -- to the degree that I restored it from an image backup. Had you come here PRIOR to the Upgrade attempt, I could have provided instructions for doing an image backup of your PC and NOW, you would have something to use to restore it.  But, it's now too late for that. Ordinarily, I would recommend using HP Recovery Media to restore your PC to its original condition. That would erase the entire drive, format the drive, and install the OS, the drivers, and the HP utilities.Unfortunately, there is no HP Recovery Media linked to the HP Product Page for your PC. This could be an oversight by HP, or it could also mean that HP no longer stocks the recovery media for your PC. They no long s... Read more

Dear Fellow Tech Users,

After successful installing Windows XP operating system, I began to attempt to connect to the internet, I have two other computers currently connected too the BT hub. With both internet connections working perfectly on those.

However, on the currently new xp installled machine, I cannot seem to connect at all. I have looked under the drivers "network drivers" and it states, "VIA compatible fast Ethernet driver (v2.66.0)" and "1394 Network adapter". So there are drivers there.

When I went too my network panel, it simply states " Acquiring IP", for which I have left it hanging there for over 2 hours with no luck. Any help would be much appreciated. I have ran driver tools but they require an internet connection to do the scan. So I'm feeling I'm in a creek without a paddle.
I am new at this computerized gizmo talk so please bare with me.

I need to know how to remove the partially installed operating system, so I can install a different one. Please help!!!!

Answer:partially installed operating system

If you get an OEM XP cd, and boot to that CD, and start the installation program, it will ask you where you want to install windows to. The partition will show you the current install.

You press D to delete the installation, then Enter and L if I recall and the partition will be gone. The you press C to create a new one in it's place and chose a size.

You will format the new partition and continue the setup process.

So in doing a new install, you will be blowing away the old install.

I wish to keep my backups on the same HDD (but on different partition off-course).
Should I just write my OS drive's image on a CD/DVD to recover windows (plus softwares) or what?

Answer:How can I backup my whole operating system plus installed softwares?

Please check this tutorial: Backup User and System Files - Reset to Default Configuration

You are better to backup to an external drive. If you backup to another partition on your hard drive and it fails, you lose everything - Windows, applications, personal data, backups - the lot.

After returning a Dell laptop that was covered in some form of vomit (Link here) upon arrival, I decided to buy a Lenovo.  Unfortunately the Lenovo (a Z370) arrived without an operating system, a PCIe controller that failed after POST, some missing and stripped out screws holding th chassis together, and a wireless card who's wires would not connect fully. In Lenovo's defense, I did buy a refurbished Z370.  However, normally refurbished computers work on arrival, instead of being dead on arrival. Naturally, I called up Post Sales and told them my problem.  They were helpful, but decided that I needed to contact Technical Support to determine the cause of the problem.  I called Tech Support, and after a 20 minute wait was told it is a hardware fault and it would need to be sent in to be fixed.  They told me to contact Post Sales again, and begin the repair process.  They also gave me a Case # WN447216 (for any Lenovo Reps here).  I called Post Sales again and was told that they cannot handle repairs and that I would have to contact Tech Support again!  I argued that I had been tossed around a few times, but the support agent would not help any further.  Now, I'm waiting on hold for Tech Support (15 minutes and still on hold) to answer so I can get a repair initiated. Someone PLEASE tell me that this is abnormal!  Any help would be appreciated.

Answer:IdeaPad Z370- No Operating System Installed

Hi rdfloyd,
Welcome to the community, sorry it has to be under these circumstances.
Yes, a refurb computer should be refurbished,
Also, your experience was not normal.  I think it was the interaction between post sales and tech support that got messed up.  Dealing with just tech support usually isn't too bad.
Tech support will send you an email asking you to print out an Inventory Control Sheet.  Make sure you list all the problems on that sheet.  Completely.  It sounds like you won't be able to list all the problems in the three lines provided, so use a separate sheet for additional problems.  Make sure you fill out the hardware that is in your system, everything.
Don't send in the battery and ac adapter.  They don't need it, unless there's a problem with either, only then send it in.
Make a copy of the filled out sheet that you're sending in.  
I sent a U160 because of an intermittent stuck key and a bios update took out the serial number in the bios.  I had it back in 7 days with a new keyboard, it was cleaned and all the numbers were back in the bios.  
Having the parts in stock or having to order parts for the repair is going to determine how fast you get it back.
My experience with service was excellent.  You won't find many customers here in the forum extolling the virtues of service. You'll see the problems here.  Customers usually don't post thei... Read more

You may try this ... Option two should work.

I've got a problem with my daughters pc, when booting up I get the error message \SystemRoot\ System32\ Config\ SOFTWARE is corrupt on a blue screen. I've found the Microsoft page with instructions on how to fix this problem, but it states not to attempt it on a pc with an OEM-installed operating system. My daughter's pc has xp pre-installed, and we don't have an installation disc. Even if we borrowed one from somebody else, would we be able to follow these instructions or would this screw things up further as it wouldn't be the right copy of xp for that particular pc?

Two questions:

Is your daughter's computer covered by any manufacturer warrantee?
Have you tried calling, emailing or IMing the PC manufacturer (i.e. Dell, Gateway, etc) regarding this problem?

Note: Even if they cannot help you with this specific registry problem; you should still ask them if they can send you a copy of an XP installation disk.

My sister recently purchased an older "refurbished" model of a Dell Dimension 8400 (that she got from e-bay). When it was delivered, she noticed that it had Win XP Pro installed; but came without the Win XP Pro installation disk. She called Dell and explained the situation. Once she was able to prove ownership of the computer - by providing the Dell Service Tag number - they not only sent her the Win XP Pro installation disk w/ SP2 included, but they also sent her the Dell Dimension Resource Disk (w/drivers and utilities).

Good Luck!

1. Your previous Windows install'll probably be stashed into another folder.
Even then, make a complete backup or an image of the computer. (I recommend Macrium Reflect since the built-in thing gave me issues in the past.)
You'll lose XP Mode, but then again you can easily get a VM running. (see VMWare Player and it's Unity mode, which I believe to be the same.

Hi all,

Apologies if my terminology isnt the best fisrt of all.

I have an XP PC which no longer boots (I get a BSOD with 'Unmountable_Boot_Volume')

As I was planning on installing Windows 7 on a fresh drive anyway, I figured I would just take the hard drive out, put it in my hard drive docking station, and pull my pictures and music from it.

When I try to do this, the drive doesnt show in the 'my computer' list. I then go into Disk Manager to try and rectify the problem. The disc is there, showing as a dynamic disc (?), but it has a little 'no entry' sign on the icon. When trying to click tohe option to 'reactivate' - it times out each and every time.

So i'm stuck now and have no further knowledge on this to be able to try anything else. Thought I would ask here before taking it to a shop, to save some coinage!

Can anyone help? Some stats below:

XP PRO SP3 (Loaded on Hard drive that I pulled from my PC)
160Gb Seagate SATA HD

Thanks a lot


Answer:Cannot access files from drive with Operating system installed

If the Disk is a Dynamic disk, you'll have to connect it internally to a Desktop PC, you can't use an external enclosure/docking station (though I've seen some reports that it does work, sometimes).
From XP Help and Support (emphasis mine):


Dynamic disks are not supported on portable computers, removable disks, detachable disks that use Universal Serial Bus (USB) or IEEE 1394 (also called FireWire) interfaces, or on disks connected to shared SCSI buses. If you are using a portable computer and right-click a disk in the graphical or list view in Disk Management, you will not see the option to convert the disk to dynamic.

Once connected internally, it should appear as a Foreign Disk. you can then right click on Foreign and Import the disk. It will then appear in Windows Explorer.

To access the files, you will likely have to take ownership of them;

I receive this message whenever the computer attempts to boot now. First time was during the first reboot of XP setup. I googled around and found it is a common problem apparently, and that the only fix (to restore 7) is to use some sort of "Windows 7 Recovery Console" which apparently doesn't exist.

Anybody have any clue how I can restore my computer? I'm no longer interested in dual booting at all, I just need access to my W7 back. >.<

Answer:Installed XP after installing 7 --> Error loading operating system

the recovery console is on the 7 DVD, looks like XP screwed up the boot.ini file for 7

A long title indeed, but it pretty much sums it all up. I have installed Ubuntu first and then dual booted windows XP. I soon found out that the fact Ubuntu wasn't compatible with many programs (even through wine) I wanted only Windows XP on my pc.
I've searched many topics, but all described how to uninstall Ubuntu when Windows was the primary OS. In my case Ubuntu is the main OS and it dual boots with Windows and I want to rid myself of Ubuntu leaving only Windows.

What do I need to do to get the desired computer setup? Or is it irrelevant which OS was installed first and will a guide describing how to remove Ubuntu from windows work as well for my case.

shouldn't matter the install sequence if you want to only have Windows. Boot into Windows and then delete (from disk management) the linux partitions.

I have an HP Compaq d530 CMT tower computer that was given to me with all components intact except a hard drive. I put a spare hard drive in it and installed Ubuntu 9.04.

This computer is a Pentium IV; i believe the processor speed is 2.8GHz. It has 512MB of RAM in it. I'm thinking about adding some RAM; I might want to try Windows 7 on this computer, probably in a dual-boot configuration with Ubuntu.

I know the computer uses 184-pin DDR memory. says it can use either PC2700 or PC3200 and that it can use dual-channel memory. It currently has 2x256MB in it. I'd like to determine whether the existing RAM is PC2700 or PC3200. How can I do that?

Answer:How to determine type of memory installed in computer running Ubuntu

Get a working OS on the hard drive, take it to crucial and let the site scan your computer. It will tell you what memory is currently installed.
Looking at the specs here:
it appears that it came with 4 sticks of 128 DDR333 (PC-2700).
Not sure why someone might replace 4 sticks with two and still have 512MB total.
Pull a stick out and post what is printed on it.

Could anybody advise me?
My brother recently bought a Hewlett Packard computer with the operating system pre-installed. He has now asked me if I can format & partition his h/d. The problem is that we only have a recovery disk and not the full setup disk.
I contacted HP (UK) to get one and they have told me that as far as Microsoft are concerned they (HP) would be acting illegally. I informed them that a few years ago Tiny sent me one for my own PC so they then told me that Tiny had acted illegally. This morning I contacted Microsoft UK for confirmation of this but was told it is perfecly ok for them to send a disk.
I then rang HP back and informed them of this but they are still refusing to issue one and tell me it is illegal.
This is not meant to be a gripe or a moan about any individual company but an attempt to gain knowledge regarding my problem.
If I can't get hold of a full setup disk how can I do a full system format, partition and re-install an operating system that he has paid to use.
Our only other option would be to buy the operating system (again) or to buy an OEM disk and hardware but surely lots of others must have had the same problem.
Thanks in advance for any advise/info/views in advance.


Answer:obtaining operating system (XP) setup disk-pre installed sofware

I think HP are behaving badly here and you might approach your local Trading Standards office about them, providing they're operating from a UK address.

That said, however, the only feasible alternative is to buy an XP CD, format, install and activate with the new Product Key to give your brother a fully legal and supported OS. The other way round this is to post details of his problems - why does he want to format? Someone here will help.

If he only wants to partition, there is software that can do this without losing data. Have a look in Control Panel>Administrative Tools>COmputer Management>Disk Management and see what the present partition arrangements are. HP may have left a small partition to store data which responds to their recovery disks.

So I turned it off and back on again a few times, and finally it booted into vista. It didnt do it again for a few days, and now here I am everytime I go to turn on my computer I have to either tap it a couple of times, Unplug the power supply from it, or open the dvd drive bay and try it again. I dont know if any of what I am doing is helping it start up or not, but I do it anyway just in hopes to get it up and going. I have do a clean install on it in hopes that it was just the Master boot record, but with no changes. I have checked the driver software and all of it is up to date.

I have a dell studio 15 laptop Windows Vista Home Premium installed on it. I got this laptop in November 2008, since then it was working fine just when I returned from Germany o india its not working. initially i thought disk got damaged due to x-ray scanning on airports but I read several threads on internet which says it does not erases/damages hard disks same I have also experienced during my several visits in which same laptop has gone through with this scanning process.

I tried to recover my OS by using OS DVD provided with the laptop. I booted my laptop by setting up the bootable device as DVD in BIOS but it does not help me to recover. I tried to install Windows XP also in C derive so that I can see the data(i.e. my all useful and important) present in D derive but its is not allowing me to install windows XP too on it.

Well, last year I installed the Upgrade version of Windows 7 and lollygagging along without thinking I put the 32-bit in. Now, after several attempts to update my IE10 to IE11 it occurred to me that either something got mangled up with the install or it wants the 64-bit version, so I want to install the 64-bit disk. After reading the bad news for this herein hopefully it is not all that much of a problem and I can recover the stuff already on the drive using the "custom" install. Am I right?


P.S., it is my Dell 1545 that had that weird 32-bit Vista on it before making it WIn 7

Answer:Win 7 32-bit installed before 64-bit, mistake

I always use 32-bit on 4gb of less RAM for better performance. What IE issue concerns you?

However compare the install you did to the one compiled in Clean Reinstall - Factory OEM Windows 7
to see how close you came to getting it perfect. You may want to do it over if it can stand a better install. But unless you want to upgrade RAM from 4gb I would still use 32 bit.

Hey. I have a processor that says it supports both 32-bit and 64-bit, however I don't know which one I'm actually running on. I have a hunch I'm running the 32-bit, considering I get an error code saying that my setup.exe is not supported by Win32.

So I have a couple of questions:

1) Very Important: I put in the my email that I used and the last 5 digits of the credit card that I used to purchase Windows 7 so I can go back to the download page ( - and it says it can't "verify" me.

2) I have a back up disc coming to my house - but I don't know whether it is the 64-bit or 32-bit version, how would I be able to tell?

3) Is 64-bit that much different than 32-bit? The reason I wanted to get Windows 7 now was because I had to wipe my computer clean just a few days ago, so I thought "why not." It seemed to be running fine on 32-bit before (assuming it was on 32bit), so what's the difference?


Answer:Installed the 64-bit version (by mistake)

Hi yoman3, and Welcome To The Seven Forums.
Could you please give your system specs, it would help us determine the system speed (32 or 64 bit).

If your system is 64 bit it is the best way to go. If it isn't you wouldn't be able to install the 64 bit onto a 32 bit machine.

I've searched the forums and realize now that it was a huge mistake installing the OS while both new drives were plugged in. Windows did an update to service pack 1 and now it will not load past the windows screen. I've unplugged the HDD where the OS is not installed and then it will boot and load windows. I'm assuming in order to have use of both drives that I will need to do a clean install on the SSD while the HDD is NOT plugged in. Once that is done I'm assuming I would then plug the HDD back in and make sure boot is set to SSD in the bios. IF that works correctly, then I assume that I would need to try to use diskpart in order to clean since the MBD was installed on the HDD and that diskpart is the only way to clear that? EDIT: maybe not the only way, but the easiest means I have available to me.

SSD is on sata 0
HDD is on sata 1

I have no information data on the drives that I need wish to keep, so wiping them is not a problem. I just need to know the proper way of completing this.

Answer:Installed Win7 with 1 SSD and 1 HDD plugged in, BIG mistake, need help

If it will boot when you unplug the HDD then have you tried setting the SSD to boot first in BIOS setup? This should cut the HDD out from booting and interfering.

Please try that now and post back a screenshot of Disk Management - Post a Screen Capture Image.

If the system will not boot at all with the hard drive plugged in then move the data off of it and wipe it with Diskpart Clean Command, repartition it in Disk mgmt as a data drive, make sure it isn't set to boot first.

Answer:Can i use two operating system in my computer

Yes you can set up a dual boot machine, but it does need some expertise, especially with win7 already on (easier if xp on and adding win 7), and does have risks (which you can guard against, but again easier with expertise).Easier approach might be installing something like virtual PC, vmware, virtual box or similar, in which you can set up and xp virtual machine to run older programs. In fact if you have professional or ultimate versions of windows 7, virtual PC 2007 will integrate into the operating system allowing you to run apps in the xp vm directly from win7. Other versions of win7 can still run virtual PC, but you'll need to run the apps inside the xp vm. Try googling to find out more details. Also a lot less risky than dual booting, and you don't have to reboot machine to use the other operating system.

Welcome to the HP Forums
I would like to take a moment and thank you for using this forum, it is a great place to find answers.

As I understand the "Operating System Not Found" Error Message Appears On Black Screen,

Here are a few steps to resolve this concern:


Operating System Not Found

This error message may appear for one or more of the following reasons:

The notebook BIOS does not detect the hard drive.

The hard drive is physically damaged.

The Windows Master Boot Record (MBR) located on the hard drive is corrupted.

The partition or section of the hard drive containing the Windows MBR is no longer active.

Solution: The Master Boot Record (MBR) is a section of the hard drive that is used by the PC to start the Windows operating system. If the MBR is corrupt, the PC will not start. The Windows Operating System Disc (OSD) provided with your HP notebook PC can be used to repair the Master Boot Record (MBR). Follow the steps below carefully to repair the MBR.

Insert the Windows Operating System Disc into the optical (CD or DVD) drive.

Press and hold the Power button for 5 Seconds to turn off the PC. Then press the Power button again to turn on the PC.

Ok I currently have an OEM MOBO with a Pentium D 925 3ghz CPU.

it's a pretty old DDR2 board.

Someone owes me ?200 and at the least I should be getting ?100, so I've found a nice AMD x4 black edition 3ghz AM3 socket CPU for only ?60, and a MOBO to go with it for ?40, so I should be all set.

But, from what i've seen myself and heard, is that a new MOBO/Processor means a re-installation of Windows 7. But I don't have my w7 disk, I haven't had it for about a year now, I can't afford to buy another copy of ultimate =[

How do I keep Windows 7 if I get this new stuff (I have 2 drives, a 200GB SATA and a 80GB IDE/PATA, my operating system is on the 80GB PATA drive.)

I know half of you love intel, but I'm not dishing out ?150 for an entry level i5 thank you.

Answer:Keep my operating system with new computer?


But, from what i've seen myself and heard, is that a new MOBO/Processor means a re-installation of Windows 7

That is correct.

You can't normally transfer an OS from one computer to another unless the hardware is very similar. At the very least you would need to do a repair install and for that you would need the install disk. Also, an OEM OS installation is tied to the computer it was installed on. You cannot legally transfer it to a different computer, even if the original is no longer operational. That is only possible if the OS was installed with full retail (not OEM and not upgrade) install disk.

Your only legal alternative is to buy a Windows 7 disk or install a free OS such as Linux.

I'm not interested in flames or engaging in religious-type discussions about operating systems. However, after nearly 11 years with the same computer, I am finally going to upgrade to a new machine. Amazingly, I've been functioning with a 450 MHz Pentium II running Windows 98 SE. Yes, it's slow and I need to restart it daily, but it still even manages to play YouTube videos and other multimedia if I'm patient enough about it. But enough is enough, and of course there is the issue of Windows 98 no longer being supported by both Microsoft and newer software.

The point is that I'm a believer in buying relatively high on the price/performance curve and leaving alone what is not broken. I'm going to build a new system with a quad core Pentium and 8 GB of RAM. Since I'm assembling it myself, I have a choice of operating systems. I'm not against Unix/Linux, but I'm not geeky enough to embrace that side of me. Grudgingly I accept that for the least inconvenience I will be using one or another flavor of Windows.

The big question is what version of Windows to install. Basically, my choices are Windows XP Professional, the 32-bit and 64-bit versions of Windows Vista Ultimate, or the new beta release candidate of Windows 7. Since it's a brand new machine, I might as well install the best choice when I set up my system.

Opinions from the collective are welcomed. However, as I said, I'm not interested in a quasi-religious debate abo... Read more

Answer:Operating system for new computer

I might as well install the best choice when I set up my systemWhen you ask a question like that, it invariably turns into a pissing match since nobody knows what is best for you, and can only answer to what they think is best. Since the Windows 7 release candidate is out, my recommendation would be to install that since you will be able to use it for a year. You can decide then what you want to do, and spend the money then instead of now.I am not a Vista hater. I have gotten along quite well with it since it came out. I also get along quite well with Windows 7 also. The only issue I have had with it is that HP has not updated my printer drivers for it yet, so it took me a bit to figure out that I needed to install it in Vista compatibility mode.

My friend's computer crashed and when she took it in to get it looked at she found out that the last person that "fixed" it used a bootleg copy of XP and that is what messed up her computer. She was told she needed to get a new copy of XP to get the computer working again. She doesn't exaxtly have the $230 that it costs at Staples, especially since she just paid the other guy $400 3 months to fix it, but he's nowhere to be found now to help her out.

(A) is running on XP Professional

Won;t really work that way since the hardware is different and you may have major problems if you do move it. The XP activation is another roadblock that will prevent this from happening. I would strongly suggest against it.

Alternatively give a look at CloneZilla and see if you can clone a copy of Windows onto his computer. The issue with this is you will need to reactivate Windows on the new hardware - make sure you have all the Windows Keys and support numbers on hand if needed.

The message you are recieving and the clicking sound are usually associated with hardrive failure, you could slave the hardrive in another machine to see if you can access it as a test and to try and rescue some data but this usually don't work.

Hi guys and gals. I'm in the process of building a new system and need to transfer my operating system and all files from the old hard drive to the new hard drive.

The donor hard drive is an IDE and the new computer will have SATA.

Operating system is XP. I have the install disc, but prefer not to lose everything else on the original hard drive if at all possible.

What is the best/safest way to transfer all of the contents of the old hard drive to the new hard drive?

Answer:Transferring XP operating system to new computer.

You can use any drive cloning program to copy from one drive to another, but keep in mind you'll need to perform a repair XP install on the hardware, at a minimum. When XP is installed with one set of hardware, and you change all the hardware, XP simply does not boot. A repair install is the minimum requirement, sometimes a clean install is required.
Here's some free drive cloning tools: (I've never used this so I have no idea if it will work for you)
There's others in the Back Up downloads section.

I connected a 60GB Hard Drive as a slave to my old Pentium 1 Windows 98 computer with a 3GB Hard Drive. I intended copying all my files on the primary drive onto the slave drive.
However, when I started the computer, at the point where it said “Verifying DMI Pool”, a cursor started flashing and this message appeared : “Missing Operating System”. I immediately switched the machine off and removed the slave drive that I had connected. But now, all the information on the 3GB Drive appears to have been lost. I keep getting this message : INVALID DRIVE. Even, when I connect the drive to another Pentium 1 computer as a primary drive or as a slave or to my new computer running Windows 8.1, the drive is no longer recognised or accessed.
Where did I go wrong? I have even tried several free data recovery software but to no avail. Only one such software managed to recover a few files but these were files that I recall I had long deleted. Is there any way now to recover all the active files in My Documents and my e-mail messages or is the situation now hopeless?
