Bug#735932: [grub2-common] Computer does not boot

Wed Feb 12 19:23:10 UTC 2014

I had the same problem upgrading from 2.00-22 to 2.02~beta2-5. I am
using LVM and UEFI in that computer, and I think that the problem is
related to UEFI. I solved this using some recent version of debian
testing installer from an USB drive and in the rescue mode:
'dpkg-reconfigure grub-efi-amd64'.
If then I run 'dpkg-reconfigure grub-efi-amd64' from the local system,
grub is unable to boot again.

>From another computer without UEFI nor LVM, the upgrade did not cause
any problems.
