I tried to go through the same steps as last time by installing win2000 again. That seemed to go fine until I rebooted and I was back to the dreaded "Error 22". So obviously that wasn't going to work this time. I had a look at what was left of the hd without ovewriting the data I want back - so i've reinstalled fc3 on a rather small part of the disk and hoped that would help. So I rebooted and again got "Error 22" yet again. Reaching for my emergency ideas I decided that maybe this was because I had installed boot on it's own partition. So I ran: #grub #root (hd0,2) #setup (hd0) #quit and started again - now it boots - I'll let you know how it goes. I'm *very* annoyed that grub can do so much harm when it is such an elemental tool for people trying to move from windows to linux - this is really an achiles heel of great significance. Also the availablility of rescue tools is way out of the league of most windows users. Going through all this has really questioned my commitment not to opensource or floss, but to linux as an alternative os. It's just too steep a learning curve and too hard for windows users. end rant. Now I just have to work out how to restore one partition without f***ng up all the things I've got to work again. thanks for the help guys, Duncan
