View Full Version : Booting ends with GRUB after update/reboot

24th May 2008, 11:54 AM

I upgraded my F8/x64 to F9/x64. That went well, and I found several updates available. So I installed those and rebooted because of a new kernel. Now the boot ends with GRUB in the upper-left corner of the screen. I have boot the DVD, entered the recovery mode and can access the installation but how I can recover from this?

Thank you.

can you just switch kernel?

how can I switch the kernel if I can't boot properly? grub.conf looks like it's ok... apparently there's something wrong with the 1st stage of grub.

You can enter recovery mode with the DVD and at the prompt type chroot /mnt/sysimage, then grub-install /dev/sda assuming you have one hard disk. If there are no errors reported reboot and see if you get a boot menu. Assuming all is well to this point you should see 2 Fedora options, the old and new kernels. Try the new one. If it fails try the old one. If that works post the output of the command cat /boot/grub/menu.lst.

Thank you. Both kernels boot. Now just wondering what messed up Grub.

Who knows? Seems to be fairly common. The main thing is knowing how to handle it and getting it sorted, which you have now managed to do.
