If you get the grub prompt, then you can issue a configfile command to tell it where the config file is located. Typically it will be something like: configfile (hd0,0)/grub/grub.conf This assumes /boot is a separate (and first) partition of the first disk. Once you have booted, you can fix this by running grub as root and then using the following commands: root (hd0,0) setup (hd0) And if you are using raid 1 and you want the second disk to be usable if the first has been pulled, you can addition run: setup (hd1) (In the raid case there is supposed to be a way to tell grub to use the current disk instead of a specific disk, but I don't think Fedora does that by default, and the above is easier to remember and works well enough for me.) At the grub prompt you can run help and there is tab completion for commands. This helps prompt your memory when you aren't expecting to use it ahead of time. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
