Ubuntu 10.10 Upgrade Problem (grub_xputs)

[jay3]

Have just run the upgrade from version 10.04 to 10.10. The process all ran ok and then at the end when trying to restart I receive the error "The symbol Grub_xputs Not Found". And, I am given a "grub rescue >" command prompt. What happened? Anyone know what I need to do now? Thank you.

I am given a "grub rescue >" command prompt. ... Anyone know what I need to do now?
See this tutorial on grub2 for info on how to boot from the grub rescue > prompt:
https://help.ubuntu.com/community/Grub2#Rescue%20Mode
If it were me, I would just cut my losses and do a clean install from the Ubuntu 10.10 install CD. I always do clean installs instead of upgrades, and I never have these problems.
However, many people seem to fear doing a clean install of Ubuntu for some reason. So see if you can follow that tutorial and boot from the rescue prompt.

I guess i didn't want to go the route of a full/new install of ubuntu 10.10 because I wanted to maintain all my setup (such as my email) and didn't want to have to backup and reestablish all my files/data etc.

Hi,
the xputs error indicates that GRUB is likely missing some files.

I recommend you use the chroot method outlined in this guide by drs305 to purge and reinstall GRUB:

(use the correct partition for your setup)

Note: if you are also booting other operating systems, then I suggest you run the boot info script linked at the bottom of my post BEFORE using the method above and post the results here so we can take a look.

If you have any questions, feel free to ask.
