[SOLVED] UEFI not detected in "BIOS" (UEFI setup?) on a GPT harddrive

Hey guys,

I have a ASUS P8P67 motherboard which does not seem to be able to spot my EFI partition and/or EFI files. It works with a MBR partition on my flash drive, but not on my GPT partitioned SSD.
I want to be able to use EFISTUB booting, which I've gotten working using my flash drive, so the problem right now is that it does not detect my .efi files on the SSD.

This is what my partition looks like ATM, using gdisk -l:

GPT fdisk (gdisk) version 0.8.4

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 234441648 sectors, 111.8 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): <omitted>
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 234441614
Partitions will be aligned on 2048-sector boundaries
Total free space is 2014 sectors (1007.0 KiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048          206847   100.0 MiB   EF00  EFI System
   2          206848       234441614   111.7 GiB   8300  Linux filesystem

This is the contents of /dev/sda1 (the EFI partition):

./vmlinuz-linux
./initramfs-linux.img
./initramfs-linux-fallback.img
./efi
./efi/shellx64.efi
./efi/initramfs-linux-fallback.img
./efi/initramfs-linux.img
./efi/linux.efi
./linux.efi
./shellx64.efi

I have no clue why it's not detecting anything.

You have to write a boot entry into the EFI bootloader: https://bbs.archlinux.org/viewtopic.php … 0#p1090040

Thanks. I'll try that.. and that makes sense now that I think of it.

I can't believe it was so simple. Thanks a lot for the help.
