Has anyone used the Ubuntu Boot-Repair-Disk on Fedora ?
I have grub error on booting on a Fedora 18 Install, and I would like to use the Boot-Repair-Disk.
I don't recommend doing this. GRUB is essentially forked by the distributions in ways that make various aspects non-interoperable. You're best off booting DVD or Netinstall Fedora media, choosing the troubleshooting submenu and then the rescue a system option. All that does is add rescue boot parameter, which then anaconda picks up, locates your installed system, mounts the parts in the appropriate places. S o then all you have to do on a system with BIOS firmware is: chroot /mnt/sysimage grub2-install /dev/sdX grub2-mkconfig -o /boot/grub2/grub.cfg exit reboot
If you're doing this on a system with UEFI firmware, it's a bit different. chroot /mnt/sysimage yum reinstall grub2-efi grub2-tools shim grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg exit reboot
Don't use grub2-install on EFI systems.
