Another way is to shutdown to single user mode. This should unmount all but the root file system. You can always do a umount -a. Make sure root is mounted read-only. (If I recall, in SuSE when shutting down to single-user, it mounts read-only, but Fedora did not. So, what I do is try to write to root, and if it fails I'm read-only. The command to mount root readonly is: mount -o remount,ro / At this point you can run fsck. I generally run fsck on a single partition at a time in this mode, but you can also run multiples. Probably the simplest way to fix the MBR is to go to YaST/System/Boot Loader. Stepping through this, should cause the MBR to be rebuilt. Another way is to use the grub(8) command. Check the grub info page: info grub There is a section "3.2 Installing GRUB natively" This will also rewrite the MBR. -- Jerry Feldman <[EMAIL PROTECTED]> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
