To answer the 1st question, probably me, when i accidentally copy- pasted some text i was editing into a root prompt. Duh. Worse, i might have screwed up the original MBR by using dosfsck. But the real issue is how to get it, Windows 2000, back? Note: the Windows partition in question is still mountable and is automounted via /etc/fstab when SuSE 9.3 boots up, but i can't boot into Windows. What happened? * I tried to boot into Win2K via GRUB last night and got this response for the first time (after many previous successful boot-ups -- comments added): root (hd0,0) #<- from /boot/grub/menu.lst Filesystem is type fat, partition type 0xc chainloader+1 #<- from /boot/grub/menu.lst Boot failed * BEFORE READING at linuxquestions.org that i might be able to fix this by replacing old GRUB commands in the Windows 2000 entry in "/boot/grub/menu.lst" (above) with: rootnoverify (hd0,0) makeactive chainloader +1 boot I TRIED THIS: # unmount /dev/hda1 # dosfsck -r /dev/hda1 and was told the MBR didn't match the one "backed up" (noting there exists a file "/boot/back_mbr", 512b in size, on /dev/hda7, in my box). Then dosfsck asked if I wanted to copy the backed up MBR to the MBR (or something like that, as choice 2) or do the opposite (choice 1) . I chose 2 (and crossed my fingers -- which didn't work, yet again). * Now, i can boot into Windows but can only get a "C:\>" prompt, with a very limited command set available. "C:\boot.ini" is still there and *looks* OK, but i'm not sure what to do and am afraid to try more without knowing more. I naively tried the alternate code, above, for /boot/grub/menu.lst, but it doesn't work (now?) Thanks in advance for any help. best, Andi
