Ubuntu Lucid Lynx upgrade breaks Grub boot loader

Thursday, May 27th, 2010

Today I upgraded my laptop, which dual boots Ubuntu and Windows 7, to Lucid Lynx (Ubuntu 10.4).  Towards the end of the upgrade it said it was upgrading Grub (the multi-OS boot loader) to Grub2.  It then asked me some questions about which partitions to modify.

Apparently I answered wrong, because when the upgrade finished and I rebooted, I got an error message from Grub: “Error 4: Symbol ‘grub_puts_’ not found“.  I ended up at a prompt that said “grub-rescue>” where very few commands worked.  Even “help” was not recognized.

Thankfully, others had blazed the trail.  A little web searching turned up a procedure for repairing the Grub install.  (Note:   the first command should be “sudo fdisk -l” with a space dash lower-case L).  I just booted from the Ubuntu LiveCD and followed the procedure.  That resurrected Grub and allowed me to boot successfully into Linux.

Well, as you might have guessed, my Windows 7 boot had also been clobbered.  To fix that, I had to boot from the Windows 7 CD and follow these instructions.

Finally, here are a couple of other informational references for Grub 2:

Many thanks to those who went before, battled the dragons, lived to tell the tale, and took the time to tell it.
