Hello, I have this layout now. /dev/sda1 swap 4G /dev/sda2 ext4 1G /boot /dev/sda3 btrfs rest of the disk. When installing I did : grub-install /dev/sda grub-mkconfig> /boot/grub/grub.cfg But still when booting I see only the grub prompt. When I do ls (hd1, and then a tab I see this (hd1,msdos1) filesystem unknown (hd1,msdos2) filesystem ext* (hd1.msdos3) filesystem btrs. What I find wierd that I thought Linux can be found at (hd0,) Regards, Roelof Wobben
