I'm missing something as system can not find boot device fdisk /dev/nvme0n1 Disklabel type: gpt
Device Start End Sectors Size Type /dev/nvme0n1p1 2048 6143 4096 2M BIOS boot /dev/nvme0n1p2 6144 268287 262144 128M EFI System /dev/nvme0n1p3 268288 1316863 1048576 512M Linux swap /dev/nvme0n1p4 1316864 315889663 314572800 150G Linux filesystem I don't want to use EFI. /boot = dev/nvme0n1p2 (ext4) file system When I run: grub-install /dev/nvme0n1p2 Installing for x86_64-efi platform. grub-install: error: cannot find EFI directory. but there is /boot/grub Running: grub-mkconfig -o /boot/grub/grub.cfg is OK (no errors) fstab: /dev/nvme0n1p2 /boot ext4 noauto,noatime 1 2 The BIOS has CSM compatibly mode enable. When I try to boot, system can not find bootable partition. Am I suppose to put any file system on /dev/nvme0n1p1 (2Mb partition) the installation manual did not mention anything.
