In the first boot after install quick error message "error: no such device " and I get thrown in the GRUB shell. I can boot Manjaro by
set root=(hd0,gpt5)
linux /boot/vmlinuz… root=/dev/sda5
initrd /boot/initramfs…
boot
After that I followed recommended steps to fix GRUB:
$ sudo grub-install /dev/sda
Installing for x86_64-efi platform.
Installation finished. No error reported.
$ sudo grub-install --recheck /dev/sda
Installing for x86_64-efi platform.
Installation finished. No error reported.
$ sudo update-grub

But despite encouraging outputs from these commands, GRUB remains broken and doesn’t boot on its own. Any advice?
