A thought just occured to me, I used to always make a copy of my mbr and save it to floppy, someone that has xp might want to try this, boot into knoppix, then as root use dd like this:

dd if=/dev/hda of=/dev/fd0 bs=512 count=1

then I could boot to the floppy mbr disk go into linux and copy the old mbr back using:

dd if=/dev/fd0 of=/dev/hda bs=512 count=1

I can't guarantee this will work, and for sure I wouldn't do it as a test on an important machine. The first part should cause no problems, ie. copying the mbr to floppy, but the writing it back? ?? ? ??

...if it breaks you get to keep the pieces...

I just thought about something, I don't know anything about windows 2000 or xp, at school we have a busted win2000 machine, if you thought the mbr stuff would be the same for 2000 and xp I'll test this on that machine, as currently we are running knoppix on that machine, because win2000 will boot but will not allow logins.
