ntfs.sys corrupted

By Daz'n'Ash ·
I have a computer that has Windows XP Professional installed with SP2. It was running perfectly until just a few days ago. The owner of the computer told me that it just suddenly flashed a blue screen (BSoD) then rebooted, and continues to flash a BSoD and reboot. It does this even when attempting to go into safe mode. Booting using the option to use Last known good configuration doesn't cure it either. The BSoD error message includes NTFS.sys corrupted. How can this happen and how can it be cured? I have tried 5 different hard drives in that computer in an attempt to install Windows again, but it won't take any O/S other than Win98 so far. Same error message, ntfs.sys. Even after a low level format.

Have you checked the drive with any diagnostic tools? Also, have you checked the drive for viruses?

You say you have tried 5 different drives in this machine and they are all giving the same error?

Have you tried this:;en-us;822800

this is the same problem caused by bad memory - very similar symptons:

and have you seen this also:

Good luck

Well, I tried all that, it didn't cure what ails it. Thanks very much for your time though. Please add any other suggestions you might have.

create dos boot floppy,
copy ntfs.sys from a system with hexp pro sp2 to the floppy ( or another one )
boot the bsod computer with boot floppy.
copy the ntfs.sys to the windows system(32) [ or wherever it was ]

pull floppy.
reboot system

You cannot access a NTFS file system with Windows 98 boot disk

To resolve this problem, replace the missing or corrupted Ntfs.sys file:1. Use the Windows XP startup disks or the Windows XP CD to restart your computer.
2. When the "Welcome to Setup" screen appears, press R to select the To repair a Windows XP installation using Recovery Console, press R option.
3. Type the number of the Windows installation that you want to access from the Recovery Console, and then press ENTER.
4. Type the administrator password when you are prompted, and then press ENTER. If no administrator password exists, just press ENTER.
5. At the command prompt, type the following commands (press ENTER after each command):
cd \windows\system32\drivers

ren ntfs.sys ntfs.old
Note This step renames the corrupted Ntfs.sys file to Ntfs.old. If the Ntfs.sys file is not found, the file is missing.
6. At the command prompt, type the following command, and then press ENTER:
copy cd:\i386\ntfs.sys drive:\windows\system32\drivers
Where cd is the drive letter for the CD-ROM drive that contains the Windows XP CD, and drive is the drive where you installed Windows XP.
7. Remove the Windows XP CD from your CD-ROM drive, type quit at a command prompt, and then press ENTER to quit the Recovery Console.
8. Restart the computer.

Some suggestions. Appears to be a very strange problem indeed.

1. While booted in Win98, run Memtest86 and check memory thoroughly. XP is tickier about memory than 98. Change out RAM, if needed.

2. Take a spare HDD and reset to factory defaults using manufacturer's diagnostics available on their web site. This should include a "low level" format which is basically writing all 1's or 0's to hard disk. Takes a while.

3. Try installing XP on pristine HDD from above and see what happens. Let us know results.

I don't think copying ntfs.sys to problem installation will help.

One other thing to try is flashing BIOS in case it is corrupt or a critter is residing there.

Good luck.

A question.

Are you receiving ntfs.sys error after install of XP or during installation process?

I have tried clearing CMOS, replacing RAM, replacing CPU and even replacing the motherboard. The hard drive will not accept any windows installations at all now. Could it be a faulty drive or something else?

after trying all the other answers
check the capactitors next to the CPU
if any are not flat on top they are bad
you will have to replaced the motherboard

good luck
