Try booting up using the XP CD-ROM and choose to repair. Then choose the Recovery Console Option... Choose the number corresponding to your XP version and enter your Administrator Password (then press enter). After that you'll see a command prompt...enter the following command: bootcfg /rebuild" command to fix boot.ini. FIXBOOT will fix the boot sector on the boot drive, FIXMBR will fix the master boot record if the NT loader complains of a missing HAL or unmountable boot volume. ""use the fix mbr command"" After the process is completed enter the command EXIT to quit (and the system should auto reboot OK from that point onwards...

also you can try to boot to the cd and run recovery console and than run chkdsk /p and than run fixboot that always fixes that problem

I had a similar problem and documented my solution to it here... http://www.salocin.com/article.php?name=21015 It's not as bad as it looks - my first impression was that my HD was fried, but it's not really that serious.
