@sradjoker what do you think about adding these to the steps here The latest grub package update needs some manual intervention
After
sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=EndeavourOS-grub
Maybe this?
cp /boot/efi/EFI/EndeavourOS-grub/grubx64.efi /boot/efi/EFI/boot/bootx64.efi
and maybe for clean up this (after you reboot and everything is working)
rm -r `ls /boot/efi/EFI | grep "endeavour" | grep -v 'EndeavourOS-grub'`
What do you think?
