Unable to boot into Windows 7: Boot critical file C:\Windows\system32\drivers\vmbus.sys is corrupt

Q: Unable to boot into Windows 7: Boot critical file C:\Windows\system32\drivers\vmbus.sys is corrupt

When i boot up my computer it doesnt reach the user login screen before it loads of startup repair. It looks for a fix but it doesnt find one. In the diagnosis the only error it shows is 'Boot critical file C:\Windows\system32\drivers\vmbus.sys is corrupt'. I have booted kaspersky repair disk and run a full scan which found no viruses or malware etc. From the startup repair window i have tried a system restore which had the same problem when attempting to boot. I can only access the system recovery options screen.

I am running windows 7 32bit, and i dont have a windows 7 disk but do have the windows 7 32bit iso file that i used to install windows 7.

I would be grateful for any help to resolve this issue.

Thanks in advance.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

but do have the windows 7 32bit iso file that i used to install windows 7
so burn the win7 iso to dvd and see if you can boot to it and run the repair

Laptop - Dell Inspiron 1525 
Windows Vista
Been getting this message on failed start up repair since yesterday. System restore runs and says its completed successfully but then it just boots up doing the system repair again. I can't even get into the computer via safe mode (to see if there are any files on there that I really need)
Is there anyway to get into the computer to get my files that I might need off or fix this problem? 
Someone told me that I'd need the Windows DVD version of my version of Windows to fix this and a repair install doing? I have no idea what that means and the only DVD I have is a recovery one I made via the laptop a month or so ago, which someone told me if I use could wipe all my data and I really don't want that to happen. 

Thank you for reading. 

A:boot critical file c\windows\system32\drivers\ksedd.sys

Try performing a repair installation.  This will require the installation disc, if you do not have one you can download a ISO image and burn it to a disc to create one in the instruction as Window Vista Forums.

During recent update Windows 7 failed to boot. Various attempts to "repair" also failed. One attempt did report it was due to a corrupt file:\Windows\system32\drivers\aswvmm.sys.
Have seen this mentioned several times here in the forum and always with a custom result. Can you help me.

A:Win 7 won't boot corrupt Windows\system32\drivers\aswvmm.sys

Any time you are posting about a problem like this it is a considerable help to list the make and model of your computer or - if it is a self-build - the main components and the details of your OS such as SP1, 32 or 64 bit. But, no matter.
Have you tried booting in 'Safe mode' - usually achieved by tapping 'F8' while the BIOS screen is showing (the one with the maker's name all over it) ?  If you have tried 'Safe mode' will it boot into it ?
If you can get into 'Safe mode', choose the 'with command prompt' option. When you get to the command prompt type 'sfc /scannow' - note without the quotes and that there is a space between 'sfc' and /scannow - this will then attempt to fix any corrupted files. When it has finished running if your computer doesn't automatically re-boot, re-boot and see what happens.
If this doesn't work for you, post back with the details of your computer and a note of what 'various attempts' you have tried. After all, there is no point in asking you to repeat something you have tried and didn't work.

Good evening all,

New to the forum and I'm experiencing problems with my desktop running Windows XP Pro.

If I try to boot I get the message System32/drivers/ntfs.sys missing or corrupt

I have searched the forum and tried to do as advised here http://forums.techguy.org/windows-xp/923352-system32-drivers-ntfs-sys-missing.html

When I try to run Windows recovery console I get a blue screen with the same message :-( at part 3. of the above advice.

I'm guessing my drive has gave up the ghost but in true tight style I'm praying it is something silly and not the drive.

Any help or advice would be much appreciated. I'm not very good at fault finding but I know my way a round a PC well enough to do virus removal etc so not totally illiterate and able to follow any instructions given to me.

Plllllllllease someone help

After getting my laptop (esystem) back from a charlatan that wanted to charge me 80 quid for getting rid of my bios password, i found the password and found that windows xp had been installed on it! the os was vista, i tried to reinstall vista but to no avail due to a message saying : windows failed to load because a critical system driver is missing or corrupt staus 0xc00000e9 file: windows\system32\drivers\acpi.sys
ican't get past this
any help would be appriciated, thanks.

A:Critical system driver is missing or corrupt staus 0xc00000e9 file: windows\system32\

hm ... I think that is referring to your HDD drivers. If you don't have a drivers disk already, then:

1.) Enter your BIOS
2.) Write down the make and model of your HDD
3.) Download the drivers for your HDD from it's manufacturer's website.
4.) Burn the driver to a disk (a jump drive might work, I can't remember)
5.) Your Windows installation menu should have a "load drivers" option some where.

EDIT: Nice catch, Archean! My tired brain didn't pick-up on that time-saving possibility.

From my Windows Boot Manager It stated that Windows failed to start. A recent hardware or software change might be the cause. My problem started after I went to the
https://www.healthcare.gov/glossary/affordable-care-act , and my google chrome requested that I kill the website for inactivity. It asked me 3 times. I told it to wait twice and the third time the program froze
and would not let me close it. I disconnected my laptop from power including the removal from of the battery. This shut it down and stopped the connection. When I restarted the computer, I checked to see if anything had affected the bios, and it did not, until
I tried to restart the OS. Then I received the message from the Windows Boot Manager. I have tried repair, and reformat the hard-drive to no effect. I wanted to find out why the affordable care act would require the use of a

Hi, i tried microsofts suggestion of renaming it to ntfs.old, then recopying it from the "disk" to c:\windows\system32\drivers.

recovery console came installed on my computer, so i did
"copy d:\i386\ntfs.sys c:\windows\system32\drivers"
it copied it back into it, so when i checked "dir c:\windows\system32\drivers" both "ntfs.old" and "ntfs.sys" were there.

i typed exit and my pc rebooted and i had the same ERROR.
my pc is a compaq presario s6500nx
before having this error i had the same error except instead of SYSTEM32\DRIVERS\NTFS.SYS it was SYSTEM32\DRIVERS\ISAPNP.SYS

i fixed that error the same way and it worked, so i am confused
as soon as i fixed the ISAPNP.SYS, i rebooted and the new error came up.

I have been locked out of my pc since Friday!! PLEASE HELP! cannot enter windows, even in safe mode. or last known good

Hello, I was downloading what appeared to be an update for Java but about halfway through the download my computer shut down and restarted.

On restart, the computer stated that Windows 7 could not load and started to do a startup repair, which did not succeed.

I opened Startup Repair and Diagnostics and the report log stated:

Boot critical file c:\ci.dll is corrupt.

I have tried system restore at several points and run sfc /scannow, which told me to reboot my computer, but I kept going round in a loop from there.

I suspect I have the exact same problem as referenced by Jan Soall and solved by m0le and farbar (http://www.bleepingcomputer.com/forums/topic396014.html). My computer is also a Toshiba and does not come with a disk to re-install Windows. I've picked up right where farbar started assisting on the thread and have downloaded and run frst64.exe. The resulting log is below.

Thank you SO MUCH for helping me with this.

I can still use windows fine, however this is a big nuisance, and i can think of no explanation of why this is happening. I have installed no new apps or hardware of any sort in the recent months either.

It is running Windows Vista Premium [ No service pack ]

I was wondering if anyone has had this problem, or if anyone knows how to fix this problem ?

The problems started yesterday when my computer went to blue screen and automatically shut down and restarted. This happened twice, then I did an AVG scan in Safe Mode. It placed several infections and a few malwares into the virus vault. However, it "did not test" dozens of files because they were "locked". There were Boot directeries that were listed among the locked files.

I restarted in Normal Mode, and got a message that Windows found a malicious file and "partially removed" it. When I clicked on the message to find details about the file, this webpage popped up: Encyclopedia entry: TrojanOS/Alureon.A - Learn more about malware - Microsoft Malware Protection Center
So the infection was TrojanOS/Alureon.A (edited to add: the smiley face appears where : D [without the space] is in the trojan filename)

About an hour later, the computer crashed and restarted again, then again a few minutes later. I did another scan and no malicious files were found.

When I turned the computer on 20 minutes ago, I got a screen telling me that the computer was unable to start, and Windows was searching for solutions. It apparently worked because I'm using the computer now. However, when I clicked to see the details of what happened, I saw this: "Boot critical file c:\windows\system32\kdcom.dll is corrupt".

So I don't know if it fixed the file or if it's still corrupt. I'm concerned my computer will have trouble rebooting. Thanks for any help in... Read more

PC spec - Windows 7 Pro (32-bit) Intel Core 2 Duo, 4GB Ram, 2x 250GB HDD

I think I have succesfully removed a Root Kit virus using Kaspersky TDSS Killler but would just like to make sure no other malware etc remains. I'll explain from the beginning.

1. PC was running fine then Windows start-up repair appeared. In the diagnostic & repair details it spotted an error - Boot Critical File E:\CI.dll is corrupt

2. could not repair, restarted, PC would'nt boot up

2. I searched online and found a thread recommending to use Kaspersky TDSS Killer.

3. the thread advised to boot-up with signature verification disabled (F10) - This worked but before I could use the TDSSKiller, the PC crashed. There was also several Trojans and worms being detected, eg: W32/Blaster.worm by what looked like windows defender, but not sure - having searched google about these, it may be a fake Anti Virus software running. I read W32/Blaster.worm does not affect windows 7? and nothing is being found on scans.

The signature verification option did'nt work after that PC crashed

4 Instead I created a windows recovery CD using a different PC - this allowed me to start the PC into Command Prompt MS DOS.

5 I ran the TDSS Killer Software directly from the a CD - after scan finished it said something about MBR, and use standard boot option, (sorry can't remember exact line) I clicked on yes to use standard.

6 PC restarted again as normal and everything seems to be running fine.

A:[SOLVED] Boot critical file c:/ci.dll is corrupt

This error has been known to be caused by Windows Updates. Every reference I've read on that issue required a re-install of Windows 7 since nothing else worked.

Provided you've taken the sensible precaution of backing up your files before that happened, re-installing will not involve losing anything. Better still, if you've created a "System Image" which Windows 7 allows you to do (& which everyone should do as soon as possible after installation), restoring Windows will be even easier.

The missus has a mini notebook (ee) that has Windows 7 starter on it. Whilst using it last night, there were some updates from Microsoft available, and I set the updates in motion.

One of them was to install Explorer 9, and I declined that, as this is the wifes computer and she uses it for work, didn't want to stuff anything up.

Delayed doing the restart for a while as i was still doing some minoer work on a Word doc.

When it went to restart, it went into a screen trying to auto fix and issue. After much time and multiple attempts, it could not do it, and any restart went into the same mode.

In the end, it could not fix the issue.

From the error report, the following message comes up ;

Boot critical file
c:\windows\system\system32\ntkrnlpa.exe is corrupt
Error code 0xa

As this is a mini notebook, it doesn't have any floppy disc etc, and I can't even get it to start in safe mode to try and fix.

Help !!!

That is the Windows NT Kernel.

Try and boot using the HDD recovery partition - try system repair from there.

While the timing with the Windows Updates may make hardware failure seem unlikely - it is a possibility.

0xa = driver referenced invalid or bad memory. It could be either software or hardware (specifically RAM) related.

Ok so here is the problem,

I come to boot up the computer

Windows XP - Home

when booting in normal mode or safe mode I get the message

system32/drivers/ntfs.sys is missing or corrupt

please insert original windows disk and press 'r' on the first screen.

so i put in the disk and it says boot CD but then after a while it just comes up with the same message telling me to insert original disk.

I have tried this now with 2 different windows disks, iv changed to boot settings and this still does not work.



A:System32/drivers/ntfs.sys missing or corrupt (Cant boot)

To restore a missing or corrupt ntfs.sys file you must have the Windows XP CD and follow the below steps.

1.Insert the Windows XP CD into the computer and restart the computer.
2.As the computer is starting make sure to press a key to boot from the CD.
3.In the Windows XP setup screen press the 'R' key to run the Windows Recovery Console.
4.If prompted enter the number of Windows installation you're repairing.
5.At the command prompt type the below command.

copy x:\i386\ntfs.sys c:\windows\system32\drivers

* In the above example you would replace x: with the letter of your CD-ROM drive. Many computers have the CD-ROM drive configured as the D: drive.

6.If ntfs.sys is still on the computer you'll be prompted if you wish to overwrite the file. If prompted, press the Y key for Yes to overwrite the file.
7.Once the file has been successfully copied remove the CD and reboot your computer.

I'm an intern with an NGO organization where one of the desktop computers started having problems about a week ago. The computer is a Dell running Windows 7. Every morning, the first person to turn it on sees a whole bunch of updates being installed. The boot screen is irregular, it doesn't include the F2 or F12 options for changing the setup, and it never goes to the log screen. Instead, it goes to a "Startup Repair" window, runs a "scan" that can't be canceled, and then reports that Windows was unable to fix the problem and offers an option to restart. If I click to see the full diagnostic, everything checks out except the last item, which says that "critical boot file ci.dll is corrupt." If I go to "Advanced Diagnostic Tools," it doesn't allow to me do a system restore or much of anything else besides open the command prompt, and I can do only limited diagnostic tasks from there. If I restart, though, it restarts and functions perfectly normally. I installed Avast on there when I started working with it and the full virus scan finds no problems. The computer functions normally for the rest of the day; however, when I go to shut it down after 5 oclock, it says that it's installing 67 updates, every single day.

I can't figure out whether this is some bizarre virus that just makes it take a little longer to use the computer every morning, or a much more malicious virus whose effects simply haven't mani... Read more

A:Can't boot into windows: system32\config\system corrupt

Hi, i know a way that you may be able to recover some files..

Download a Boot Disk (live CD) from Ubuntu. download it and put the ISO onto a disk, this will allow you to get into the pc and look at the folders on the windows side of things.. you DONT need to format to get this OS working. after you have the files simply put them onto a Ext HDD

You could try a windows repair but try a /fix mbr and /fix boot if poss. if not just repair it should just replace the missing file if not, format. but simple really.. use ubuntu to grab ur files..

Windows XP attempting to boot, stops with error msg (in Safe Mode also)"missing/corrupt ISAPNP.SYS file" error msg specifies \system32\DRIWERS, not a typo, is DRIWERS instead of "Drivers". The file is located in the Drivers folder, apprehensive about using XP CD to repair or do in place upgrade.

Recently McAfee techs worked remotely on computer, suspect was typo on their part or malware.

Where can I modify this path name? Or what is best approach to repair without reinstalling everything?

I am running windows xp professional. I have two hard drives plugged into a PCI-IDECMD0680R-2 IDE Card, setup on RAID Mirrored set.

On boot up I get Drive Number: 0 HDS728080PLAT20 78533MB right below this it reads Drive Number: 2 HDS728080PLAT20 78533MB right below this it reads Set: 1 <0> (2) SiI Mirrored Set <PM> 78532MB

The next pop up text reads: Incomplete Raid set ! Please press F3 to enter Raid Utility.

If I do not hit F3 and let the computer continue to boot the next error message I get is Windows could not start because the following file is missing or corrupt: windows\system32\config\system

Now let me tell you what I have done to try and diagnose this problem. I tried to run UBCD hard drive test on both drives while hooked up to the IDE card but the drives do not recognize. What i did next is unplugged the drives from the IDE card and plugged them into the main ide controller one at a time on the system board. Both drives recognize and hard drive test passed. Also the computer will boot into windows with no problems when the drives are plugged into the main IDE controller on the system board. So, I think my drives are good but I just need help getting raid set back up without loosing my data. Thanks and I look forward to any help!

Hi there guys I have Windows 7 RC and have been using it it for months without any problems.

I installed Microsofts new AV program and that was running fine, I guess. Today I installed a wireless keyboard and was playing around with it and the system crashed. I restarted it and when it came to the boot screen (mine is dual boot with Vista) it just restarted. Tried Vista it came up with boot load error. I tried the RC disc to repair and first it said it fixed it but tried again and nothing. So I was thinking about re installing OS again, went through the setup and windows said it could not install on disk 0 partition 1 as that had a boot system, it just would not show that HD at all even though it has other partitions. When to the motherboard setting and there it only shows 1 WD HD and the Pioneer DVD-ROM. My system consists of the following
1 X Samsung 1TB, several partitions inc OS for both Win 7 and Vista
1 X WD 2TB, 2 partitons
1 X WD 2TB, no partitions

The Samsung did not show up nor did the other WD
I have now opened the case and plugged the samsung via USB to my XP machine and all partitions show up, on Win 7 the boot file is messed up and the Vista partition has no boot file at all.

How do I fix this guys. I dont mind re-installing Win 7 but there must be another way to do this, any help on this will be much appreciated thanks in advance guys

Can you use something like EasyBCD running from your XP box, but linked to the other HDD?

I don't have my W7 or Vista box with me now, so I can't remember how the bootloader works on them off hand.

I guess another thing would be to try and load W7 on a USB drive and see if you can gain access to those two partitions. If so, worst case, backup the data, fix the partitions, and then overlay the data to get it back.

Windows could not boot because the following file is missing or corrupt:

Have tried the recommended MS fix .using XP CD and "expand d:\i386 " command but I am getting "the system canot find the file or directory specified".

Any ideas ? I think my HDD is either damaged or has picked up malware implying it is damaged but data (apart from OS) may be intact...don't want to reinstal from recovery and lose data (although "my documents" folder has been backed up to external HDD) if I can repair XP but seems not to be possible. Using repair from recovery console doesn't show any current WIN XP installation and C partition seems to be "empty" (shows 148mb of 160mb HDD "free")

A:Windows could not boot because the following file is missing or corrupt:

Try booting from one of these. Don't even bother trying to replace the "missing" file because it is probably not missing and there are 7 choices of hal.dll decided upon at setup, so you may get the wrong one.

Bootable XP Sysboot Floppy and CD Images

These will give you a menu for boot and you choose the partition and drive. Most will be the first choice. If it boots, then we just need to fix your boot.ini or other boot files.

Can you give us the make and model? Do you have a SATA drive?

So sometime randomly during the night, my computer restarted itself due to like finish installing some Windows updates, then I awake to find my computer in the setup recovery screen! This is not the first time this has happened! This EXACT same problem occurred about 2-3 days ago, so what I do is I check to see what the setup repair had found and apparently A file called " D:\ci.dll " is a critical boot file & it's corrupt, and now I don't know what to do!? I don't have ANY restore points, no recovery disc, and have no idea what to do which is why I came here. Should I get the file from the same version of Windows 7 from a different computer I have & replace it using Linux booting off a CD? Or what would be the best solution? Because last time, the same file was corrupt, and I did a system restore, btw, if it helps, I have an Acer, 6Gb of Ram, Windows 7 64Bit, 3.2Ghz AMD processor, AMD Radon 6570.

I have an old Dell Dimension DIMC521 desktop running Windows XP with service pack 3. Recently my brother was using the computer and accidentally opened up a bunch of instances of the same game. It was going really slow so he tried to turn off the computer normally, but he eventually just held the power button down to turn it off. When he tried turning it back on he got a blue screen with the error:

The Session manager initialization system process terminated unexpectedly with a status of 0xc000026c (000000000 000000000).
The system has been shut down.

(The numbers in parenthesis may have been a little different). After looking around on the internet he decided to try the recovery console using the XP installation disk. He did a chkdisk r on the c drive and then restarted the computer. This time we got a different error:

You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair.

After looking around some more he found out you could copy this file using:

So I've done some research but after being thoroughly confused I figured I would make a thread about it.

I have a Dell Inspiron 1520 with XP SP2 installed. Served me pretty faithfully for three years, then recently I had to force a shutdown by holding down the power button. Usually this causes no problems, but this time when I started it back up it wouldn't boot into Windows, instead telling me that "Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM". I can get into the Recovery Console and that's about it.

I saw a similar entry on Microsoft's support website, but it had a warning for computers with XP installed by the OEM (which is mine). I also can't seem to locate an XP Recovery Disk that supposedly came with the laptop.

Is there some way to fix the problem (which apparently is registry-related) without erasing all my data, and without a Recovery Disk? Any advice is most appreciated.

A:xp wont boot, says "\WINDOWS\SYSTEM32\CONFIG\SYSTEM" is corrupt

Just an update: I was in the Recovery Console, and ran C:\WINDOWS>chkdsk /p. It finished checking without any issues, and it didn't fix anything when I exited and rebooted.

Hey there I've been having a few problems with my computer recently. My computer has been regulary crashing. However it always booted. But recently my computer has to decided it won't boot at all. I have a feeling that my computer may have been shutdown incorrectly and thus the problem may not be linked to the random crashes which I believe to be the result of installing a new graphics card. However I cannot be sure of this. One thing I am sure of though is that I cannot do anything unless I can boot my computer. I've already posted on the possible graphics card issue here on this forum and made mention of this boot issue there, however I've now linked the no boot issue here, since it may be a seperate problem.

Last night I tried to watch a video on youtube, but the clip would pause after a second and no audio would play. Also one of my sub picture folders had become corrupted a few days ago. A similar problem occurred a couple weeks ago. I made a topic here and was told to schedule a chkdsk. I did and it fixed the problem. Since my computer always runs chkdsk at boot for some reason, I restarted my computer and let chkdsk run. I then got a dos looking screen that said "file windows\system32\config\system is missing or corrupt." My jaw hit the floor.

Using a PlayStation 3, I went online for a solution. I found a forum that said to boot up the Windows CD and press 'r' to begin the recovery. it then press '1' and type "chkdsk /p" Then type "fixboot" Finally reboot, press F8 and choose "Last known good configuration" I did all this and got the same problem, a corrupt windows\system32\config\system file message.

Then to top it off, my Windows CD stopped booting up! It would say it's loading but then take me to the same corrupt windows\system32\config\system file screen. I later read that som OEMs won't be able to get back into the Recovery Console if you do a fixboot. I don't even know what an OEM is?

I am hoping someone here can offer me assistance, oh yes also! (i took the HD, put it into this pc as a slave, copied the important files to an external in the hope that i could reinstall windows.

At this stage i am stumped, i think the HD may have been damaged from excessive vibrations caused by the pot holes(trenches) that existed on the journey. Irregardless i would appreciate the assistance.

A:"windows Could Not Start Because The Following File Is Missing Or Corrupt: \windows\system32\config\sys...

This error means that Windows was not able to load the \WINDOWS\SYSTEM32\CONFIG\SYSTEM registry hive. It does this early in the boot process in order to initialize many Windows functions (the rest of the registry loads much later in the boot process).The reasons for this are many, but the clue here (IMO) is that you installed the OS on another system. Windows has setup that disk to use the hardware in the other system - and it's balking at all the hardware changes that it sees (along with the different security descriptors that are generated in each system). This is likely to be the cause of the failure to load the registry hive error that you mention.The best thing to do (again IMO) is to put the disk back in the system that you installed it on and boot it up. Then uninstall all the hardware devices (other than the motherboard and CPU) that you can. DO NOT RESTART!!! Once everything is uninstalled, shutdown the system and then remove the hard drive.Put the hard drive in the new system and boot directly to the CD with the XP installation files on it (ensure that you do not boot to the hard drive as this will start the process that we're trying to avoid) and perform a repair install ( http://www.michaelstevenstech.com/XPrepairinstall.htm ) Presuming that there are no hardware issues, this will enable the new system to boot successfully.More info here: http://www.michaelstevenstech.com/moving_xp.html

I have an E-machines T3265 PC. It came with bundled software.

When I booted it on Sunday, I received the following message:

"Windows has failed to start because the Windows/system32/config/system file is missing or corrupt."

My question is this: Can I correct this problem if I have an OEM software package (bundled software)?

With the massive amount of research I've done over the past 2 days, it appears that if you have the basic windows installation - a windows package not bundled with other software - that this is a pretty easy thing to fix - you simply use the "recovery" system. Well apparently, with a bundle, you don't have that option.

My bundle does not appear to have a "repair" feature. It has a recovery feature which restores the PC to its original state. Is there any way that I can repair the registry without having to restore my PC to its original state?

NOTE: The I386 file is contained in my C:\Windows folder as opposed to the root directory of C:\.

NOTE: Aside from having the original disks at my disposal, I have set up a second hard drive which contains a complete and updated (through SP2) version of Windows. This was set up using the same disks as the failed hard drive so they are virtually identical where windows is concerned.

NOTE: I have Accronis installed on both hard drives but the one that failed only has a data backup, not a system backup.

Ok! I suggest you do this:
Insert your window's XP CD and start your computer..If u r prompted to press a key to contninue do it.
When you see the welcome screen press F10 so u can get to the recovery console or just wait till the OS read the hardwares of your computer and take you to a menu from where u can press R (repair)
Once on the recovery console type 1 If u have one OS on your machine..
Type the Administrator's password when u r prompted to (if u assigned a password of course, if not press enter)..If you use XP HOME EDITION just press Enter (Password is blank).
Go to config by typing this: cd c:\windows\system32\config (If the prompt was C:\Windows> just type CD system32\config).Your prompt will be:
C:\Windows\System32\Config then type this command: ren system system.bak
You will get a message stating system was renamed.

Copy c:\windows\system32\repair\system c:\windows\system32\config\system a賘nd press Enter..A message will show u that 1 file was copied.
Retrieve your CD and type EXIT to start your computer again.
Good luck.

I know a version of this forum has been started on here, but everything I have read, it is being said that they need to use the OS disc and run the repair and all that. But this is a Netbook with no CDROM drive. USB and SDcard drives, that's all. Is it possible to repair this without the CD? Even the onscreen message is the same message everyone gets, "You can attempt to repair this file by starting Windows Setup using the Original Setup CD-ROM." But no drive to do this.
It is an ASUS Netbook
OS is XP

A:Boot issue on netbook, missing or corrupted file Windows\System32\Config\System

Do you have or can borrow an external DVD drive? Then go into the BIOS and change the order so that USB is first boot option. Samsung and Lite-on do USB powered DVD RW drives made to use with netbooks, no doubt they could see a market for them with the millions of netbooks being sold ! Then you need an OS disc of the type you are using, and you can try a repair.

Hello Forum,

My wife's computer won't boot. I get the message, "Windows can not start because a file is missing or corrupt" System32\DRIVERS\pci.sys

It appears that the CD ROM was not operating properly for awhile prior to this problem although the computer was operating. Since the error message, the monitor has quit as well. The monitor will now not operate with or without being connected to the computer. I suppose that this may be just a coincedence.

I have searched the internet for fixes for this problem with System32\DRIVERS\pci.sys and have found numerous bits of information, advice and fixes but I still have not had any success. I tried using the XP Setup Boot Disk with no success. I was in the Recovery Console with no success. The Restore CD that came with the computer did nothing.

I am also looking for a way to tell if the CD ROM is working or not. I am wondering if there is a way to access the DOS window even though the XP is not loading and I have no access to "Start" or "run" etc.

Thanks for any help,
