I am having issues booting and end up in a grub rescue shell.

Searching around the web, i have found some commands to get a bit more information about my system.
Running sudo fdisk -l gives

      From which we can see my main drive is /dev/sda and the root and swap use lvm.
      The /dev/sda and /dev/sda1 have the boot flag. It is pretty much a standard unbuntu installation. The /dev/sdb is the usb drive i am using right now to run my computer.



      To me, all seems fine and i am out of idea on how to get my desktop back. How should one approch this problem to solve it?



      Thanks,
