unknown operating system after repair

Question: unknown operating system after repair

Hello. I have a dell laptop (Latitude D600)running windows xp. I did a system repair with the dell disk. Now when I reboot it gives me a choice of operating systems - windows xp is first then below that is unknown operating system. I click the xp and it loads great. How can I get rid of the choice and also I would like to get rid of the files that the unknown system is using if possible. Thanks so much in advance for any help.

Preferred Solution: unknown operating system after repair

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.)

Hi, turns out that when i get to this window:

Instead of "Operating system: Windows 7" i get "Operating system: Unknown" and when I try to repair startup, it fails, what could be the problem?


Answer:"Operating system: Unknown" when trying startup repair


Try this article MBR - Restore Windows 7 Master Boot Record and if that fails this one How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

I've been trolling the forums here for a while. Lots of great info but now I actually have an issue where I need some assistance.

When I was booting one day last week I got a nasty BSOD when Windows was trying to load. Then on the next reboot Windows 7 said it couldn't load and needed to do the recovery OS option from the Windows 7 repair on the CD. Well, before trying that I did a cold reboot and it got back into the OS fine so I didn't think much of it. Now, I noticed Ghost shows the C: drive status as "Unavailable" and it can't back it up anymore. It does give me an option to restore from one of my old backups. I'm thinking the MBR got hosed up somehow or something like that. But I'm skeptical to run an MBR repair since I have that 100MB partition on my SSD where my OS resides.

Ghost Shot>

This was about a week ago my Windows 7 started acting up right before the big patch Tuesday. I've been running it for over a year now and it's been solid. When I first set it up I installed it on my SSD (Intel 510 120GB) drive. One of the qualms I had with the install is Windows created a separate boot sector on the disk drive where it stored my boot files. This is known the the "system reserved" operating system files 100MB partition. Apparently the way to avoid this is to use a third party partition tool before doing the windows install. That way it will keep the Boot sector files on the same partition which is how I would of liked it for doing resto... Read more

I'm not sure if this forum supports Windows installed on a MacBook,
but I'd appreciate any help provided.

Regarding my laptop, it's a MacBook Pro bought around 2011,
witn Windows 7 x64 installed from my friend's disc.
(Sorry I cannot remember exactly what it was)
"Barely alive" condition.
Works fine, but suddenly shuts down at times, alert shows battery not inserted (UNDETACHABLE on this MacBook model), won't run without power adapter connected, immediately shuts down when inserting USB cable into 1 of the 2 USB ports, won't detect internet connection, and so on and so on......

That aside, it worked fine until last week.

I was running Windows Update when I accidentally insert USB cable into the wrong port and "forced shut down" the laptop.

When rebooted, I get a flash of BSOD and auto-restart, which leads to startup repair.

From there, I ran startup repair a few times, each time I get the successful result yet Windows still won't start.

Then I switched to Mac OS to use it for some urgent stuff.
While in Mac OS I did went around and did "repair disk" and stuff to the bootcamp.

Next I tried searching for solutions through my phone and did this and that on command prompt.
chkdsk bootrec etc etc tried all posted solutions to something similar to my case.

I'm running Vista Ultimate 64 on a 500 Gig hard drive with 3 partitions.The problem is I marked one of the partitions,not Drive C, as "active" by mistake.I done a Command Prompt to make it "inactive", but when I started the system up again it wouldn't boot.I used the Vista disk for the recovery process, but I got a message "Operating system unknown on (unknown) local disk" i tried fixing the problem with a command prompt "bootrec/fix boot" ,but nothing happened.When I look at the info in Command Prompt it doesn't show the disk partitions, just Disk 0.Also I can't repair because no Disks are listed to be repaired. If I look at the drive in "My Computer" it is full with a file system marked as "Raw" and it wants me to format the drive.I used "Recover My Files" software and it shows some of the documents that are on the drive, but doesn't show any recovery.I looked at some internet post about the message I got and partition and boot problems like I have, but at this point I don't to try any else to make it worse.I would do a reinstall ,but on one of the drives I have some stuff that wasn't backed up.I never thought about backing it up because it wasn't on the C drive.Any help to solve this problem would be appreciated. ..........Kumpie

Answer:Operating system (unknown) on unknown local disk


Try marking the C partition as active again, using the Windows method in my post here.

Then run Startup Repair from the repair disc. Hopefully it will see your installation.

hi, my computer is running windows crashes a lot. i ran a check with says i have an unknown operating system. it also says:browser detected microsoft internet explorer version6. slow boot up and computer crashes a lot. can anyone help me with this please?

Answer:unknown operating system

Have you tried anything else like defragment ?Your main problem is you are using ME . Sorry but it just won't work very well on some systems and there's not a lot you can do about it, or rather no matter how much you try it will always give you problems with some setups.There is nothing wrong with IE version 6 it's the updated version.Have you been using Windows automatic updates ? They can be troublesome with ME.You could try BigFix available from click here to update you system with the necessary patches.

I have an Asus G74S. It was working fine yesterday except for being connected to our usual home wifi yet not getting internet. Our other computer, a Mac, accessed it just fine as usual. When I tried to restart my Asus, it only gave me the option to restart Windows normally, which loops me back to the same menu, or enter System Recovery. I tried the system recovery scan 3 times (it took hours each time), restarted between each, and it just keeps bringing me back to the same menu. Perhaps it's because the screen says that it's an unknown operating system.
I can't use a System Restore because the computer says it can't find the operating system and that I need to restart and choose one, though when I restart, it brings me to the same menu and I don't see a way to choose an operating system.
I don't have a recovery disk, but I do have 3 Windows backup disks I burned when the computer was new. I was able to get into BIOS and switch the boot order to load the DVD drive first, but it just asks me if I want to load the disk image, which I don't want to do since that'll erase my files and programs.
The option to choose a system image doesn't automatically detect anything. I have the option to select some drivers. When I open that menu, I can see that my two hard drive partitions (D and E) have their remaining space and files listed, but C is blank. I can open the contents of that backup disk (I just tried the first one), but I'm not sure there are even drivers on ... Read more

Answer:Unknown operating system, won't boot

I would remove the hard drive...and connect it as a secondary drive on a different system.
I would then try to run the chkdsk /r command on the troublesome partition.  If chkdsk /r reports that it cannot complete (via onscreen error message), please post same.

5 Recovery CDs i made at time of purchase are not recognized when loaded.

how may i recover, repair or reinstall the operating system ?? thanks - jimhicks36

Answer:how do i Repair or Reinstall operating system

If the recovery CDs aren't being recognized it's possible they didn't burn correctly when you made them.

To do a Repair Install you'll need an installation disk containing the Windows 7 version currently on your machine. This Repair Install tutorial contains a link to Digital River where you can download an official ISO for your operating system. The ISO would then have to be burned to a disk or USB flash drive. A repair install should preserve your user accounts, data, system drivers, other installed programs, etc.

Repair Install

If you prefer a clean install to remove factory bloatware and unnecessary "stuff", this tutorial explains how that can be done.

Clean Reinstall - Factory OEM Windows 7

There's one other possibility that might work for you. Your Aspire might have a hidden recovery partition on the hard drive that could restore the machine to factory specs. This Acer FAQ sheet explains more.

I Have a Toshiba Satellite M50, I was today running a virus scan in safe mode and must have deleted a system file accidentally because now i can't log in.
The computer will boot but when I try to log in it will log me in, flash my desktop back ground once and then log me out again.
Can I repair the operating system without resetting the whole hard drive and losing all my files?

And if not, is there someway to boot into a DOS prompt because i no that the file is still in the recycling bin and i might be able to restore it.

Answer:Re: Can I repair operating system without resetting the whole HDD?

Hello Bambi

Repair option with recovery DVD (recovery image) is not available. Using recovery DVD you can install OS and have ?factory settings? again.
As far as I know into DOS level you can boot using DOS start disc. You can create bootable CD.

Can you start your notebook using ?Safe Mode??

So the other day I got a pain in the butt virus (GFW I think it was) . Well I ran Malware-Bytes and got the infected files off. And I started up the computer again and it looked very weird. So I went looking to see if all my files were there and they were all hidden. Fixed that but it still looks weird. So I did a repair install of Windows and it still looks the same. My next step is a complete reinstall of Windows (waiting on an external I just ordered). I was wondering if I need to go that far or if there is a setting somewhere that is doing this.

Any help is appreciated, Thanks.

So last night I was listening to iTunes when all of a sudden my music stopped and the hard drive light stayed on steadily. I decided to reboot the computer, and lo and behold when the BIOS splash screen went away, it said the "master boot record missing, press ctrl + alt + del to reboot" or something to that effect.

I quickly looked up how to repair this, and it seems like the Windows 7 installation disc is really good about repairing problems nowadays, so I gave that a shot after following instructions on some website. I hit "repair my computer" and then I tried to choose an operating system, but there were none in the list! How can I get my operating system to show up so I can choose to repair it using the installation disc?

Hi everyone hoping you can help me out.
I have just formatted an old IDE drive connected to my computer - and when i restarted I recieved an error: "Boot MGR is missing" press CTRL ALT DEL to restart.

Obviously i forgot that when i installed Windows XP around 6 months ago that the boot manager was on the drive i just formatted and therefore have deleted the boot manager.
Consequently i cannot boot into my newly installed windows 7 or windows XP.

My next move was to put my windows 7 disk in the drive and use the repair utility. However my problem lies when i come to the menu: "Select an operating system that you want to repair" - I have neither windows XP or windows 7 available to select i.e. there are no options. Despite this, when use the option "if your operating system isn't listed, click load drivers" - all of my hard drives are then listed.

Does anybody have any suggestions?

p.s i tried the XP recovery utility also - but when i select which the system to repair - it asks for an administrators password - which it keeps claiming is incorrect when i enter it but i swear it not. weird.

To Mark Partition Active press Shift F10 at first screen when booting DVD or Repair CD, or choose Command Line from Repair Console's Recov Tools list, type:

SELECT DISK 0 (confirm from list this is WIn7 HD #)
SELECT PARTITION # (replace # with WIn7 part #)

Now return to Recov Tools list to run Startup Repair - Run up to 3 Separate Times with reboots to write MBR to Win7.

Hi, I apologize if this isn't the right subforum but I saw a couple old posts about this in General.

Yesterday one of my kittens knocked my laptop off my chair causing it to hit my PC tower on the way to the ground. My tower immediately froze and when I went to restart it manually I accidentally pushed the reset button instead. (It's the button on the right) Upon doing this my computer restarted and gave me the Missing Operating System error.

Since then I have tried several things from pressing F8 and specifying the drive to boot from, to entering several commands listed here to booting from my Win7 disk and running startup repair. This final option I did a couple times last night rather uneventfully but today it failed. Under problem details it gave me this:

Problem Event Name: StartupRepairOffline
Problem Signature 01:

Problem Signature 04: 0
Problem Signature 05: unknown

I don't know if this information is relevant or helpful but I thought I'd include it anyway v0v

edit: I just told Windows to go ahead look for a solution and it claims I have an attached device that needs to be removed, which I don't.

edit2: Would a total reinstallation of Win7 fix the problem?

Any advice is appreciated.

Answer:Missing Operating System/Startup Repair Failure

First, I would open the tower and check to see if all the connections to the hard drive, etc. are still secure.

I recently ran a malware scan and had some issues. After restarting the system i can no longer boot to windows. Here's some things I've tried and run into so far:
If i run the windowx 7 ultimate repair cd my operating system doesn't show in the list.
If i let the computer boot normally, i end up with a blank screen and flash upper right hand side cursor.
The only way i've been able to get into safe mode is when the repair disc is running, but then its just the repair disc safe mode and not the actual system safe mode.

Something else i noticed was that when i checked my bios boot priority order it's all messed up, so i change it, save and restart. But then if i go back in its just reverted back to the way it was.

I need some guidance here on what's going on and how to fix it.

The information about the BIOS settings not being saved got me. Try reseating the CMOS battery. I suggest you replace it if issue is not resolved. This can also be a case of the mobo being toast. What I also need you to do is run hard drive diagnostics since your windows 7 os cannot be found.

I bought a Thinkpad X1 Carbon 3443 laptop on the black friday sale in November 2013. Due to demand, the unit didn't ship until after Christmas. I didn't complain, but Lenovo offered a 5% rebate for my troubles. Still waiting on that to be processed.I've had all the documented problems with the Intel 6205 wireless card that are all over the forums. I finally upgraded my router just to resolve the issue.In March of 2015, after the warranty expired, one of the hinges broke. I took it to an authorized repair facility and was told (after 4 weeks) the part was no longer available. I called the service center listed on the website. They offered to ship me a box so I could send them the laptop for evaluation. Since it was out of warranty I would have to pay for any repairs.After two weeks, they sent the laptop back. They never contacted me during the process. I didn't get any quotes on the cost, nor did I authorize any work. They say they fixed the laptop. I can see the hinge is physically fixed. However, I cannot start the laptop. They wiped all my data, including the operating system. I have all my files backed up,  but since this laptop does not have a CD or DVD drive, I don't have a way to reinstall the OS, which is Windows 8.1.Also, today, I received an invoice, saying they charged my credit card for what is almost the cost of a new machine.

Almost a year ago, I tried to do an XP and Windows 7 dual boot on my laptop. A few weeks later, I didn't need the XP, so I deleted the partition XP was on. I continued to use 7 though the xp still remained in Windows boot manager upon startup.

A few days ago, in the advanced system settings, I disabled the bootable OS display, and set my default OS to Windows 7. I restarted and now I'm stuck in a continuous startup repair loop, where it tells me that it can't fix my problem automatically and that the cause is an "OS version mismatch". Could it be trying to boot the partition XP was on? I can't log on my computer at all.

In the command prompt that comes up after I go to the system recovery options screen, I tried to fix the boot options using bootrec / commands, but so far none of them have worked.

Any help would be greatly appreciated

Hey all! I am pretty new to this kind of Win7 issues, so I hope some of you will be able to help. Story goes...

After few hours of gaming the computer died. (It happened right after switching keyboards.) Now, on every setup BIOS(?) comes up with list of options (F2 enter BIOS, F11 boot options, F6 Flash etc.). After that a black screen with error message comes up: Missing Operating System.

I tried rebooting from USB (since I have no disk-drive) and I keep on getting the answer: Error Loading Operating System.

Any ideas?


Answer:Missing Operating System/Error Loading Operating System

All unlikely, but possible - (a) your HDD died. (b) your bios became corrupted (c) your HDD boot sector became corrupted (d) your HDD partition is corrupted.

Does the drive spin up when you switch on (feel it)?
Check the bios to see if the HDD is reported correctly and is at the top of the boot order.
Find a bootable CD - an OS installer, or create Easeus partition manager bootable CD and boot from it. What does the HDD look like with Easueus?

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?

This may should like a stupid question but I am not sure so I felt that i should seek assistance from on of the most reliable places I know of.

I have a system that I want to give away but i cant give it away with the current operating system as it is under educators license. Currently the system is running windows xp pro.

yes you can. if you have NTFS and want to put back win98 or winME you need to format the volume with FAT32. you can use a win98 or winME startup diskette. or you can download one from .

I've been unable to access my custom build computer since around 5:00 yesterday. I chose to restart my computer at around that time just because it was slowing up a little and I usually do that to help, I had not installed any updates or new programs since 2 days ago when there had been a few windows updates.

Upon returning to my computer I noticed that it had been unable to startup and had gone straight into system repair with it being 'unable to repair this computer automatically.' I rebooted several times and noticed that it was not a visible BSOD but as soon as the 'starting windows' icon began to appear it went straight into startup repair. I tried to boot into safe mode, tried to load previous good configuration and all of the other advanced recovery options (including system restore/image and many command prompts).

This is what it shows after being unable to repair automatically:

Problem signature name:Startup repair offline
Problem signature 1: 6.1.7600.16385
Problem signature 2: 6.1.7600.16385

I am involved with a small band of new user older generation silver surfers.A question that keeps cropping up, is the re-installation of the various operating systems, mainly ME and XP Home with a little 98se.They want to know [in printed form]what will or could happen if they inserted their operating disk in their computer.Would this re-install, reformat or destroy their system. This question came to light recently, due to the fact that a couple of people are having boot-up, crash or similar problems and they want to try some of the technical stuff themselves. Using the advantage of this forum may ease their concern a little.A warning as to what can go wrong or perhaps best be avoided, would be appreciated.

Answer:Re-Installing Operating Systems for the Unknown.

the worst that can happen is they may lose their data if they accidentally format the drive with disk, you should tell them to back up all important data before considering putting the disk in the drive, even if it's for something relatively simple, back-up, back-up and back-up again!!

I was in the process of updating several sata controllers and chipset drivers. I also installed a new USB 3.0 hub and was in the process of moving around several devices between ports. I had a problem with my keyboard which uses USB 2.0 as a connector but I would recieve a "Unknown USB Device (Port Reset Failed)" code 43 on every port on the USB 3.0 Hub. I finally gave up and put the keyboard back into the 2.0 ports on my motherboard. When I finally fixed everything. I realized my DVD drive was not working. I had to reconnect the SATA cables because it got disconnected while I was moving my PC around. Upon the last restart of my PC.

I checked Disk Managment and noticed lots of system reserved partitions and drives which were not there before. I have no idea what happened but I think updating several drivers and the combination of reinstalling USB ports via device manager or the optical drive being reconnected may have messed up how windows used to have system reserves as partitions. I only had one visible system reserved drive before, now I have 2 visible and lettered system reserved drives.

I also have a unknown partition at the top of the list, I cannot right click that partition and select any options. The only option in my context menu is Help which brings me a link to Overview of Disk Management

Answer:Unknown Partition - Unknown File System - Cannot edit or remove!

Hello taqiyya6 Welcome to the Ten Forums!

Your problem is actually quite basic. You are going into the Disk Managetool and seeing system reserved partitions mounted and assigned drive letters where they shouldn't be seeing any! The 450mb partition is there to allow changing from the MBR type primary to the GPT type usually seen with server set up or large volumes exceeding 2tb in size such as installing and partitioning a new 2.5tb, 3tb, 4tb, or even one of the latest 5tb drives.

The sight of the System Reserved partition being present on the second Disk 1 500gb drive simply shows that had previously seen a Windows installation on it at some time likely before adding in the large 1tb Disk 0 drive you have the present install on. The most likely to succeed option for taking care of the smaller 500gb if nothing is on it would be a complete wipe and a fresh single partition intended for storage and backup. That would eliminate the first SR but not small second unless using an open source type partiioning utility like GParted while still an option to close up the small gap since it is only a 500gb and not exceeding the 2tb mark.

For cleaning the mess overall however going into the Device Manager and knocking out drivers before a full restart would allow Windows to redetect the drives fresh without seeing the System Reserved and MBR parts mounted again at least on the OS drive being the main concern since the SR part has to remain invisible as a system protected space not mount...

I have decided recently to create a system repair disc in case something goes wrong with my computer. Using recdisc.exe, I created a system repair disc and everything worked out fine. Once I booted with the repair disc, I got a screen that looks like this:
This is what I wanted

I decided to make a recovery USB as well for convenience. (USB is much faster and is less bulky than a regular DVD)

I copied everything in the DVD, and pasted in my USB (the USB is an active and a primary partition). When I boot into the USB however, I do not get the System Recovery Options screen, but the HP Recovery Manager screen. I personally dislike HP recovery manager and want to get the Windows System Recovery Options screen.

If I try to close the HP Recovery Manager, a dialog pops up asking if it should close HP Recovery Manager and reboot. Can someone tell me if I did something wrong to create the USB Recovery drive? I don't know what I did wrong, I copied everything from the disc (which works perfectly) to the USB (which suddenly decided not to work.) In case anyone was wondering, the HP Recovery Manager looks like this:

Answer:BSOD, Startup Repair, System Repair and other errors on nearlly new PC

These crashes were caused by memory corruption/exception (probably a driver).
Please run these two tests to verify your memory and find which driver is causing the problem.

If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

If you have Raid > update its Driver.

*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+

Driver verifier

Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

So, I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you c... Read more

I have an old HP Pavilion 8260 that I got for free which is having some odd issues. Any time I try to boot, I get one of these 2 errors (first it was always Operating System Not Found, now it's Missing Operating System).

The hard drive is dectected in the BIOS, as is the CD Rom and floppy drive. It properly recognizes the amount of RAM.

After using FDISK /MBR an rebooting, I get "Missing Operating System".

Tried installing Windows XP after formatting, it seems to have installed but it's not loading.

Hello everyone and thanks in advance for anyone that helps.
I am really troubled as I have been googling the hell out of this and trying many solutions with none of them working.

1) My pc first entered a loop when I tried to remove mcafee with their official remover. After the required reboot it could not enter windows no matter how time passed so I had to power it off.

2) Because I didn't like powering it off in the middle of something asking me NOT to power it off, I tried to system restore to a restore point 1 day prior to the event.
The system restore failed and gave me this error I believe 0x80070091
Googling to solve the problem asked me to rename the hidder windowsapps folder which requires some tinkering to do so. I tried to change the ownership and although I followed all the steps I could not rename this folder.
3) I then decided to try a system repair instead. It also failed and gave me this error C:\Windows\system32\logfile\srt\srttrail.txt.
Googling suggested that i do a chdisk or something on command prompt which I decided to not do before I backup my things since in the past I got wiped.

4) I backed up my computer and decided to do a windows 10 system reset. There are supposedly 3 options. A) reset but keep your files, B) reset but keep nothing and C) factory reset.

First time user here, desperately seeking help(right before work, that's smart T_T) Roughly four to five months ago my partner bought me a factory refurbished laptop to replace my old one that was slowly dying. It's a Toshiba Satellite C850 running Win7 home premium service pack 1 64bit. For ages it ran just fine. Then out of the blue it wouldn't boot normally. I could get it to run in safe mode but after trying system repair and restore it still wouldn't boot normally. So I backed up my files and formatted to out of box condition. This seemed to work for awhile. Then again with no warning I was unable to boot normally, I've forgotten how I fixed it that time but I remember it only worked provided I never switched it off. However after windows installed some updates I was forced to restart and the issue resurfaced. After fruitless attempts to fix it I ended up just formatting the damn thing again. It was running fine for roughly a month and now today it's having the same issue. It was running fine all night and there didn't appear to be any issues after shutting down.

I've booted in safe mode with networking to try and find some kind of solution to this issue without having to format again as it's getting to be tedious.

Hey guys:

I'm an idiot!!! Last night I deleted my System Volume Information folder off of a Raid-0 set of hard drives. As I mentioned, this raid set is not drive with my XP on it. This is just a drive for storage of pictures, video, and other programs I prefer not to have on my C:\. I did take go as far as to turn off System Restore before deleting it. Now when I boot up I cannot access the drive at all. It tells me that "The drive is not formatted. Do I want to format it now?."

I don't want to do that and I am wondering if there is a way to create a new System Volume Information folder so I can access the drive again???


Answer:Deleted System Volume Information Folder on a Non-Operating system drive???

I think you are connecting the dots...where there is no connection.

Deleting a system volume folder...isn't possible by me, even when system restore is not used (I always disable SR immediately after a clean install). Even though the folders are empty and I don't have SR employed, the system won't allow me to delete these empty folders.

I believe that the problem is your RAID setup...perhaps you ought to try to repair it.

This morning I attempted to perform a system restore on my other computer. I legally own Microsoft Windows XP Home Edition and was using the 3 system restore CDs provided by my manufacturer at the time I purchased the computer. If it matters, the computer is a Sony VAIO AMD Athlon.

I inserted the disk before booting up the computer, and everything seemed to go fine. The system restore screen loaded and I chose to do the recommended system restore, erasing all the files from my drive and restoring to the computer's original configuration.

It began performing the normal "Restoring Drive C:" operation. About 20 seconds into the restore, I received this error message:
Disk Access: Sense Operation Failed

I hit "Okay," the only button available. I then received a message saying the system restore failed and my operating system may not perform correctly (what an understatement). I removed the system restore CD and rebooted my computer. I now get an error message, "The operating system has failed to execute." I can't do anything, except try to do another system restore, in which I receive the same "sense operation failed" error from before.

I tried calling their tech support to which I was told (after waiting 20 minutes to speak to someone) that because my limited warranty had expired, I would have to pay $19.99 per call to have it fixed.

I would guess that your CD is scratched or unreadable for some reason or that the CD Rom isn't reading properly. Give it a good wiping.
I would just format and reload XP if you have a fully licensed disk. Takes 39 minutes or less and you'll have a nice clean install and you get to start over. However....... if you have only restore disks I am unsure as to whether you can do an install from them.

I re-installed Norton Internet Security 2006 with ONLY their firewall running.(LiveUpdate was run too) I did not install Zone Alarm free due to compatiblity problems. I did install Windows Defender but was told not to run it with Norton due to possible compatiblity problems.

I know this has been a topic, but the setup here warrants a new thread. Be warned. This is a long explanation. I have a known problem with making walls of text. So, I have a Flex 3, and I've had some of the most outlandish problems with this thing. I've fixed one (all keys type 6), and the rest have bizarrely fixed themselves after plaguing me for months on end, but that's aside the point.After going through a ton of crap to allocate more storage to Ubuntu (I only edited the C: partition through Windows, so that wasn't an issue), Ubuntu was asking for a swap drive password on boot (hitting enter bypassed it, I don't know why). I was following instructions to fix that, and on the last step, I accidentally edited the partition /dev/sda6 instead of /sda9 (my Linux swap partition). In a cruel twist of irony, data recovery software fished out OneKey Recovery for me. I put it in my (Windows) documents folder and removed it from the Ubuntu storage space. OKR is 19GB, and I had just added 20GB to the Linux partition, so I wasn't about to leave it on Linux's file system.I have OneKey's files and even the old UUID of the partition, and Windows booted after all was said and done. So why would I put this on help forums?Well, the next day (or two days later, I forget), I went to start Windows 10, fully expecting it to work. I hadn't messed with anything since I last booted it. I'd mostly just messed with Remix OS, which is Android. Not much I can screw up there....and ... Read more

Hey guys. I have an Acer laptop with Windows 7 that has crashed and will not boot. I do not have a Windows 7 CD nor do I have the money to pay for one. When my computer boots up, it says "BOOTMGR IS MISSING" and I press Ctrl+Alt+Delete and it loops back around to that page. I created a System Repair Disc and that boots up fine. When the System Recovery Options come up, no operating system is listed for me to choose. I can't do anything from here and I have not found any solutions so I came here. Any help is appreciated!

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%.

Is the Win XP Home still there? Or did the system restore delete it? If it's still there how can I delete it? What do I do?

I have been reading the forums and it seems that my win7 desktop has an issue with the system restore virus/worm/trojan. I was searching the web for information on teens huffing chemicals using Firefox & Google search. One of the pages began playing some annoying video, when I went to close it out I was presented with the same windows and warnings described in this post

normally I would not post on forums concerning issues such as this. I prefer to find the fix myself but the malware seems to have taken itself to a new level on my desktop. I cannot even get F8 to work. The computer launches the MSI screen that offers the press delete to get to the bios and tab to switch to post but only the delete button works then if I let it load all of the way I just get a back screen with the little DOS line flashing but I cannot type anything onto the screen. The only keys that seem to work are control alt delete to restart the computer.

I have been reading through a lot of posts on these forums concerning this issue but have been unable to find one quite the same as my present situation. It would be great to be able to save the information on the hard drive but I just spent a year in Korea and while I was gone my wife misplaced the backup and start-up disks for the desktop.

Is there any hope or should I just trash the hard drive and start over with the desktop?

Thank you

While doing some heavy video work, I managed to overheat my system spectacularly, resulting in the smell of burning plastic, all my fans going at 100%, all lights on the PC going off and all buttons becoming unresponsive.
I pulled the side off to see what was going on and found a desert of dust in there. Possibly somewhat foolishly now that I think about it, I left it running with all the fans roaring away and directed my desk fan inside the case while I went and got the vacuum cleaner and an air sprayer and got most of the dust out. (Still with the system running. No, I didn't touch anything while doing this. The vacuum was held well out of the case, just to suck up the dust cloud.)
I then rebooted it and it died in exactly the same way soon after. Through subsequent repeated crashes, I have established that it goes off at roughly 1 minute and 42 seconds after the "Do you wish to enter Safe Mode?" screen is dismissed. Any delays (such as being in the BIOS) prior to and on that screen do not affect the timing.
Very oddly, safe mode works perfectly, and I can't see the bios complaining anywhere (not that I am remotely familiar with the BIOS.)

Booting into Windows Recovery - crashes
Booting into an Ubuntu LiveCD - crashes

Recently questions were raised as to what functions are available on the System Repair CD - Create that Windows 7 will create and burn to a CD.

These clips are are from a 32 bit CD I made:
Insert the CD in the CD / DVD drive and reboot the computer.
When requested, "Hit any key to boot from CD."

Select the Language and click next.

Windows will search for an Operating System to repair.

You can choose to restore a System Image you created,
or go the Recovery Tools screen.

These are the same utilities available through the Install DVD,
or via the function of the 100 MB System Partition (if installed).

Tapping the F8 key before Windows loads (Safe Mode) opens this menu:

Selecting "Repair Your Computer" also opens the "System Recovery Options" menu,
but requires a password to proceed.

I am trying to do a system recovery back to the original condition and I have taken what I need to save. I have talked to HP tech twice and 1 told me I need to buy a special automated recovery cd from them. The other said not to do that and I need to use the two cds I have (1. operating system cd, 2. Applications and Drivers dvd). Operating system is Windows XP professional on a HP laptop.

I have completed the following steps. Can any one tell me if I am doing the right thing?
1)I put in the operating system cd and shut down the computer.
2) I started it back up useing the cd (by hitting any button when it asks).
3) I press Enter on the next menu to "set up windows xp now"
4) I press F8 to agree to license agreement

Answer:Question about using Operating System CD for system recovery

Yes, you can delete the partition; then create a new one in the same space and format it and continue the installation. The warning you see is just that you are about to delete the partition containing the current XP. The drivers CD will have everything additional you'll need, but after you regain internet access you may want to download from HP's web site and install the up-to-date drivers.

Hello everyone,

I am trying to do a system restore from the install disc because I can't boot. I followed this tutorial: System Recovery Options using method two. At step 5, the only operating system listed is Vista (which I don't have and never have had). If I select it and try to continue, it tells me that that version of windows is not compatible with the install dvd I am using. If I try to continue without selecting Vista, it tells me I have to select an OS. I have also tried startup repair to no avail.

Background information: This is on my early '08 Macbook Pro. I was using windows 7 professional x64 through boot camp. A few weeks ago after updating virus definitions for AVG, windows would no longer boot. I found that it was an issue with the update and that a system restore would solve the problem. Unfortunately, I can't get system restore to work properly.

I would appreciate any help. Happy Holidays!

im looking to upgrade my desktop from an xp to 7. system builders are very cheap which concerns me. What is the difference from a system builder and the regular version

Answer:system builder vs. regular operating system

Ok basic difference is that the system builder (OEM) is supposed to be sold with hardware only.

Other differences.
1. Retail windows can be removed from one computer and put on another legally.
2 System builder is tied to the Motherboard and is not allowed to be moved by Microsoft. I have in the past had to call in on a OEM where the motherboard went and was discontinued to get them to activate with the new hardware.
3. System builder will not upgrade VISTA like the upgrade version will do, It will do a clean install always except that it will do a upgrade of itself if started from within windows. Sort of like a repair install. If you boot off of it, it will only do a clean install and will offer to move your old windows and users folders to a windows.old directory.

That is the main differences off of the top of my head.

So nothing wrong with the system builder version for a new computer, It is what I used.

One other thing you will have to reinstall all your software and settings when you go from XP to Windows 7 as they do not do upgrades that retain those things even the upgrade version will move your old windows and do a clean install.

Good Luck

I used to think that there was something up with the 'system' file running in processes because it often times dials out to something when I'm connected to the net.

Before my fresh reinstall and putting in COMODO 4, I attempted to block system but it gets to the point where after system has tried to get through for several days the computer stops functioning properly.

So this time I left system alone but COMODO, through it's own default set up, has been blocking something called 'system' and 'windows operating system' which persistently knocks at my firewall.

So I am asking, is COMODO, through it's own default instict, in the right by blocking these?

And if these are trojans, where can I find and delete them? My scanners don't pick up the files and COMODO will not show a path to the files that are making these attempts on my firewall.

Answer:System wants to reinstall Windows operating system

I'm not sure what you mean by "Windows setup program", but if your PC is trying to boot into PXE, then check to make sur eyour mouse and keyboard are securely connected. In fact, I'd suggest removing and re-installing. The last M50 IBMs I used were setup in the BIOS so that if there wasn't a keyboard attached, it would try to PXE boot rather then booting from the HDD. This is because that's the sequence that was selected for an "error boot" in the BIOS. Hope this helps!

After running through it, it restarted and did the same thing. Now 3 days later, it's still in that process where it installs updates, goes to system repair, restarts and starts again.

I tried interrupting it and doing a System Restore, but even at the earliest date on it, it goes right back to that repetitive process. Now I can't get to any of my files or anything else on there. I'm stuck, and I need some help please!

My computer has been freezing randomly and I need to do a hard reboot to get it functioning again. After doing a system restore, the issue was still having so I brought it to my local store that is an authorized repair center. A week later they returned my laptop insisting that there is nothing wrong but that there was occassionally an issue with some bloatware in the Lenovo image so they uninstalled it and then the issue didn't reoccur. Fast forward less than 48 hours since bringing the system home and it's freezing up again. Any suggestions would be appreciated since they claim it's not hardware. 

Answer:Windows 10 System freezing, warranty repair claims system is fine

Hi Iroc24,
What anti-virus and other security are you using? I presume that the repair shop made sure your Windows 10 has all updates.  As far as other applications, have you checked to see if any of the software that the shop removed, returned with automatic updates? Do the freezes happen when you are working offline or while using a browser?

2)i cant create a dvd for repair system,i click on create disk repair and next,and says that there are some missing files........

Answer:system recovery deleted every time + cant create system repair disk

1.  You're actually talking about two separate things here.  Item #1 is "restore points", not system recovery.  This restores your system back to point "X" in time.
2.  The second item is "system recovery", with recovers the system to factory specs.
The system recovery, which is usually a partition on your computer.  If this partition is damaged, removed, or files are corrupted, you have only two basic choices:
1.  Order recovery DVDs from the manufacturer; or
2.  Purchase a boxed copy of the OS, and download the drivers from the manufacturer's website.
Have a great day!

Last night i closed my laptop without shutting it down. I woke up this morning and turned it on and it went to the system repair screen and ran through that. It says there are problems but they are not automatically repairable. I then tried to do the system restore to an earlier point in time and had one option for a couple days ago. I ran through that but it says there is an error and when i expand to see the error one of the things listed is no OS installed.

I have windows 7 64bit.

Does anyone here have any idea what might be the problem. I am very confused as to why it would say i dont have an OS installed but it is running through the system start up repair as well as listing a date that i could restore it back to.

I would really appreciate any input on this as i have a lot of data on that hard drive and i am really hoping its recoverable and not totally hosed.

I have not tried installing the hard drive into a new computer yet. I will try that a little later.

Once again, i appreciate any and all suggestions and help. Thanks.
