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

Question

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
