By the way, just putting up an entry that should have been put up last week but I couldn’t because the site wasnt online:

If you have a Windows NT based system (NT 4/2000/XP/2003) and you lose your boot record yeah, “lose” it does happen in windows you can fix it by booting off the 2000/XP/2003 CD (your NT CD may not be bootable), entering the manual rescue mode, and typing “fixboot”. This will restore your boot record from a previous backup.
Thats gotta be one of the smartest things Microsoft ever did…NT makes a backup of the boot record every time it changes and successfully boots…
