Hi I have updated my dell T7500 desktop to Ubuntu 12.04 and when I tried to reboot I got grub rescue mode.
I have booted to live cd and used boot repair as instructed here: https://help.ubuntu.com/community/Boot-Repair
At first I tried default repair but it didn't solve the problem, here is the first paste: http://paste.ubuntu.com/6761969/
Then I tried many options like purge grub, install it on only one partition (I tried several options) and at the end I did a default settings repair again and after this last one only windows boots automatically and I don't even get a choice of OS.
Here is my last paste: http://paste.ubuntu.com/6762811/
I don't know what else to do, I don't want to reinstall, how could I fix this? thnks
EDIT: I had also tried following these instructions on grub rescue Recovering from 'grub rescue>' crash but unfortunately it says something about linux not found
