GRUB can only be installed in this setup by using blocklists. Grub-install: warning: Embedding is not possible. Grub-install: warning: this GPT partition label contains no BIOS Boot Partition embedding won't be possible. Thanks again for any help!ĮDIT: So, tried a solution to the "failed to get canonical path /cow" error, got a different error sudo mount /dev/sda2 sudo mount /dev/sda1 sudo grub-install -root-directory=/mnt /dev/sda If anyone has any more suggestions, I'd appreciate hearing them. So following advice from another answer on askubuntu I tried to change the boot order (sudo efibootmgr -o 4,0,3) so it would load ubuntu first and got this error:Ĭould not set BootOrder: Interrupted system call Next I ran efibootmgr and found out that: usr/sbin/grub-probe: error: failed to get canonical path of `/cow' I've tried several more things based off suggestions from around the web, but each solution hits an error :-(įirst, I tried to manually update grub using: The only things that successfully save between restart are changes to time and date.Īny help you can provide would be greatly appreciated as my laptop is basically a brick at the moment. I have found another error but I don't know if it is related: I am unable to save any changes made in the BIOS menu - after restart all the changes have reverted. I've double-checked that the Live USB is definitely using EFI. I've checked the BIOS menu and SecureBoot is definitely inactive, and in the config menu UEFI is selected. I've tried re-installing from the Live USB to no avail. Using the Live USB I ran boot-repair, but it told me there was an error when repairing. I installed Ubuntu 17.10 choosing to erase the entire disk and previous partitions (Windows 10 & KDE Neon).Īfter install I got the dreaded "No bootable device - please restart" message. Thanks in advance for any help you guys can provide.
