Bug#766213: grub2 not working after latest updates (Debian Jessie)

[Undefined User]

package: grub2

severity: critical

Hello,

After latest Debian Jessie (testing) updates, grub2 is not working.
Actually, there's no boot loader being showed. I check every update
list, and I saw that grub2 was being updated today, so I think it's
something related to some new version.

As I cannot run my system, I ask you to please help me on getting it
working again.

I know that you`ll need more information about my system. Just ask and
I`ll get it to you (via Debian Live).

Thanks.
