I posted a thread explaining what I did. I am copying it here. Maybe it can help you. Errol Thread entitled " lost my grub an the way to 12.04" A funny (and annoying) thing happened when I upgraded from 11.10 to 12.04 beta. I did the upgrade as described on the Kubuntu site with the "kubuntu-devel-release-upgrade" command and everything went smoothly. I took a long walk, had a cup of coffee and came back to the computer to be asked whether I wanted to remove obsolete packages. I did and then restarted. That's when my troubles started. After rebooting, instead of getting the GUI grub menu I got a grub menu (the same grub menu I always had) typed in the bios format. When attempting to go into any of the grub menu lines I got a message "partition not recognised" and no amount of changing the grub with the "e" command fixed any of that. My solution was to boot my computer using the "super grub" disk. I then got into my perfectly upgraded Kubuntu and was able to work. BUT every time I rebooted I had to use the "super grub" disk. Eventually I did apt-get install (grub) and removed and manipulated the apt-get with all sorts of suggestions (such as use -f). When eventually the apt-get install grub installed without errors (after many trials) the computer was able to reboot and go to my grub and work without "super grub". Wondering if others had a similar problem and why all this happened on what was a really smooth upgrade.I am very happy with 12.04 and everything is working well despite it being a beta. Well done Kubuntu developers (with or without canonical help).

Any ideas what might have happened and what I should do? Regards Steve <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
