Also, please explain MBR while you're at it, thanks!

mbr is related to the files for system booting; when I used to mess with linux I had to change it too, I guess it needs to be rewritten, did you back up your mbr?

I wonder if it can be repaired with PE

Boot with the XP installation disc and choose to repair the system

I didn't make a backup (which finally led to reinstalling the system) 5555555555.......， I'd like to ask about “rewrite MBR”: does it mean rewriting the old XP MBR, or the MBR after it was overwritten (the one that boots straight into DOS)? A serious newbie thanks you very much! [ Last edited by slx8528 on 2009-2-7 at 15:50 ]

I think it's a partition boot record problem. The DOS and XP mbr are the same. You can install grub and directly load ntldr.
