No, já jsem právě nevěděl, jaký grub.cfg myslíš a tak jsem si připojil EFI oddíl na sda:

sudo mount /dev/sda2 /media/user

a v /media/user mám:

/EFI/Ubuntu/grub.cfg

Tohle je v tom grub.cfg:

search.fs_uuid f9c53f3f-cffb-490b-bfde-c53d7336e331 root hd2,gpt1 
set prefix=($root)'/boot/grub'
configfile $prefix/grub.cfg

Výstupy se shodují s tím, co mi hlásí grub rescue:

sudo vgdisplay lvm | grep UUID
sudo lvdisplay lvm/rootfs | grep UUID

pripadne sem dej svuj /boot/grub/grub.cfg(z SSD s hlavnim OS)

Jak se k tomu mám dostat?
