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.

Are there any messages on the screen?

Anyway, this probably means that your system is misconfigured and is
installing GRUB to somewhere that doesn't correspond to where your
system actually boots from, resulting in the core image and modules
being incompatible.  Please post the output of:

  debconf-show grub-pc
  cat /proc/mounts
  ls -l /dev/disk/by-id/

(You'll need to chroot into the installed system before running at least
the first of those.)

I forgot to say that there's no message on the screen. My system goes
to network boot directly (even when selecting HD to boot).

Colin Watson,

I believe that some of them didn't work.

I'm sorry, but I won't be able to give you other information about this
bug. I couldn't wait and I had to install Debian again. I work with this
computer.

Thanks!
