Problem booting up, got big problems

I was on the computer today and installed a few devices (webcam and sony MP3)
and then restarted the computer.

Then on restart I got problems

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

1.Insert you windows installation disc and restart your computer.
2.Chose your language settings, and then click “Next.”
3.Click “Repair your computer.”

If you do not have this disc, contact your system administrator or computer
manufacturer for assistance.

File: ndisrd.sys

status 0xc0000098

info: windows failed to load because a required file is mission or corrupt.

I bought the computer from a friend so I dont have the vista installation cd. I
dont know what to do


It could be a virus. Can you plug the HDD into another PC and run a virus scan?

You can also try this bootable scanner from PCtools LINK


do i need to take the HDD out of the base unit and put in another computer. I will give it a go thanks

I did a google on ndisrd.sys.In general it is viewed as a virus.
Some recommend a complete reformat.
I looks like you can’t do that.
If you have a Linux disc.boot with it & delete ndisrd.sys from C:/Windows/System32/Drivers/ndisrd.sys .

The Linux disc I used for things like this is TRK but there are quite a few.
the command is: rm ndisrd.sys
If you use TRK it will be something like this.
Boot from your DVD drive after setting it as the first in the startup sequence in BIOS.
When it completes the boot:
mountallfs -g
cd /Your HDD/Windows/System32/Drivers/
Your HDD will be something like sda1.
ls is the directory command like dir in DOS.
It will probably be too long & fast for you to see if ndisrd.sys is there.
rm it anyway .If it is not there you will get a not found message.I can’t remember the exact message.
After deleteing the file Ctrl\alt\Delete . The disk should eject.Remove it.
Your computer should then try to boot to the HDD & Windows.
If you still get the error message .Then the above didn’t work.
If you can get a Windows repair disk you may be able to do a System Restore from a restore point.
Hopefully someone more familiar with Linux will also post.My knowlege of Linux is limited.

You can do either one, try the bootable scanner first, see if it can find and remove that file. If not, pull the drive out and connect it to another PC that has a good up to date antivirus software and connect it as a slave.

Thanks for all your help.
I managed to borrow a vista cd from a friend and rebooted and repaired the problems as far as i know. I managed to back everything up now but i do hope it wont happen again

thanks again
