When your computer starts, the BIOS attempts to find the primary hard drive's active partition to read the first sector for the MBR (Master Boot Record), it uses that info to load the rest of the OS. For Windows NT4/2k/XP the NTLDR (New Technology Loader) takes it from there. If you get the "NTLDR is missing, press any key to restart" what's most likely going on is the BIOS either didn't look for the right drive, didn't find the right partition, it wasn't active, didn't find the MBR, or the MBR didn't list NTLDR in the right place, or the location of NTLDR changed.

Have you got a system restore disk?

Hello sreerules,

Here's an alternative method.....

http://support.microsoft.com/kb/320397/en-us

What you will need is an empty floppy disc, and go to another computer, and copy the boot.ini ; ntldr ; and NTDETECT.COM files to the floppy disc, and then boot up the 'crook' computer with the floppy.

To find the files go My Computer > right click on your C: drive > Explore, and you should see them listed in the right hand pane.

Having said that the other computer must have the same OS i.e: if the 'crook' one is Xp Home; then, the one you copy these files from must be Xp Home too,. The same applies to Xp Pro.

Once you've got the computer booted, got to the link I've given here and read about contacting Microsoft Support to obtain a copy of Bcupdate.exe.
They will email it to you, and you just run it, but don't expect too much, as its a DOS file and just flashes on the screen.

After thats all done with, I recommend that you do this...

Insert your Xp CD [hold the Shift key down to prevent it from starting], then go Start > Run type in: sfc /scannow [please note the space betweeb the c and /] and let it run.

This is the Windows® System File Checker, it checks the integrity of all protected Windows system files, and replaces them if necessary. The procedure usually takes about 15-20 minutes, and whilst SFC is running, please do not do any other work on the computer, just let it run uninterrupted.

During the operation, sfc might ask for the Xp CD, just click retry and let it do its thing.

When finished, reboot the computer, and all should be fine.

Any problems, just post back.
