I installed debian on my laptop and everything was fine (I may need to mention that I'm using LVM) until I reached the grub point. Since I have a GPT partition he refuses to install properly. I skipped that stage and I just installed grub on a pen drive in order to boot on linux. The pendrive boots successfully but when I hit the console and try to boot my kernel there is no way I can see my ssd drive. Here is what I'm trying:

  1. From the grub console: insmod lvm
  2. Then: set root=(<tab> but the autocomplete shows me hd0 only which is the pendrive itself.
  3. GRUB+LVM wiki suggests I should type something like set root=lvm/volumegroup-volume and so did I. Then, when I try to do linux /boot/vmlinux etcetc the command fails and it tells me error: disk 'lvm/group-vol not found' [I obviously used the proper names instead of group-vol]

My laptop is a samsung series 7 ultrabook.

Any hints on why is that so?

UPDATE: I booted with the netinst again and entered the rescue console. I mounted my disk and copied the initrd and vmlinuz on my usb pendrive. I can now boot BUT it stops when it tries to find the root device with something like:

Gave up waiting for root device. Common problems:

  • Boot args [etc etc]
  • Missing modules [etc etc] ALERT! /dev/mapper/group-vol does not exist.

Dropping to a shell!

Apparently, the initrd doesn't have all the modules needed to handle the LVM. I'm kind of lost because I copied the initrd created by Debian during the installation, the one expected to work...
