Fix the MBR in Windows XP

[beyond3d]

Well thanks for the tips, but on my HD both the FIXMBR and FIXBOOT commands did not do the trick. In the end, this is how I solved the problem:

I added an old 1GB hd to the primairy IDE controller, connected the drive I wanted to repair (a 40GB Maxtor HD) to the seconday IDE controller, installed windowsXP on the 1st drive (the 1GB drive). The broken disk was a Maxtor HD. I downloaded maxblast 3 for windows (not the floppy version or ISO version, which both should work also) and run maxblast 3 from the freshly installed XP. I corrected everything on the Maxtor 40GB drive (setting it as boot drive and making a new 15GB partition with NTFS).
Maxblast copied everything from the 1GB XP OS and builds up a new OS on the new partition. Shutdown the PC, removed the old 1GB HD and started the PC again...DONE

KUDOS to Maxtor!
