Need Help Configuring Grub (Libreboot) to Load LUKS Encrypted Parabola Logical Volume Group

colorpurple21859 · 05-31-2019, 09:29 AM

is this a gpt or msdos drive? add either
insmod part_gpt or
insmod part_msdos

Your /boot wouldn't happen to be on a separate partition and if so what is the partition formatted as?

Huh... that's weird. Running

Code:

sudo gdisk -l /dev/sda

says

Code:

MBR: not present, BSD: not present, APM: not present, GPT: not present. Creating new GPT entries in memory.

Erm... I don't believe so. Still new to this terminology, but I don't remember specifically making a partition for my boot directory. How would I check this?

What is output of:
sudo fdisk -l
That is a lower case L

fdisk -l gives the following:

At the grub prompt does this give you a grub menu that works?

Code:

cryptomount -a
set root=(lvm/matrix-rootvolume)
configfile /boot/grub/libreboot_grub.cfg

Running that skips past the menu you mentioned, then says

Code:

error: can't find command 'inmod'. Press any key to continue...

but then it loads me into my operating system after prompting me for my password... huh, interesting. So that works! But I'm not sure what to do to have that automatically run when I boot my computer.

The inmod error is a bad line in your libre_grub.cfg. You should be able to delete that line. Your other problem seems to be with the grub.cfg in you rom, that searches for the libre_grub.cfg file and loads it

Ah, misread that line. Deleted those insmod lines. I thought Libreboot was supposed to automatically load libreboot_grub.cfg? How do I go about changing the ROM's grub.cfg?

The link in post 10 tells how, but you have a good chance of bricking your system if something goes wrong

Ok... well how can I do this without bricking my computer?
Like I said, the guide says that there is no modification required if I don't flash the ROM. Libreboot is not loading my libreboot_grub.cfg, which it is supposed to do.

by being extremely careful other than that there isn't much I can do to help you out with that one.

colorpurple21859 · 06-01-2019, 05:24 PM

The only other thing might be is there is a /dev/mapper/root and a /dev/mapper/matrix-root for the drive throwing libreboot search function out of whack
