I did something incredibly stupid. I was trying to fix some booting issues with Vista and XP (this was a dual boot system with both OSes installed), and followed some advice online rather blindly and uncritically and now am in this position.
Basically, the advice was to use mbrwiz to wipe the MBR and have Vista repair it. The steps I followed were:
Boot to Vista DVD and run at the command prompt:
MBRWiz /Wipe=MBR /DISK=0 /Result MBRWiz /Wipe=HEAD /DISK=0 /Result
And no, very stupidly I also didn't back up the MBR.
What this did, according to the documentation of MBRWiz was:
- Firstly wipe out the MBR. Should be recoverable with Windows though (which I have tried to do)
- Secondly wipe out the first 63 sectors of the first partition of the disk
What I've tried since:
- testdisk (can only see a single "FAT32 partition", rather than the three partitions that used to be there)
- bootrec /fixmbr (same as fixmbr. Claims it fixes things but then nothing boots)
- Windows repair (can't seem to do anything)
I have most of my files backed up, so it's not catastrophic, but I am keen to restore my system to how it was. Any advice on how to recover from this?
