-===== UEFI boot loader does not show up in firmware menu =====
-On some UEFI motherboards like boards with an Intel Z77 chipset, adding entries with efibootmgr or bcfg from the EFI Shell will not work because they do not show up on the boot menu list after being added to NVRAM.
-This issue is caused because the motherboards can only load Microsoft Windows. To solve this you have to place the .efi file in the location that Windows uses.
-Copy the bootx64.efi file from the Arch Linux installation medium (FSO:) to the Microsoft directory your ESP partition on your hard drive (FS1:). Do this by booting into EFI shell and typing:
-<code>
-FS1:
-cd EFI
-mkdir Microsoft
-cd Microsoft
-mkdir Boot
-cp FS0:\EFI\BOOT\bootx64.efi FS1:\EFI\Microsoft\Boot\bootmgfw.efi
-</code>
-change boot order
-<code>
-# show
-efibootmgr
-# change
-efibootmgr -o 1,0
-</code>
-force ubuntu on ACER bad
-<code>
-mv EFI/Microsoft/Boot/bootmgfw.efi EFI/Microsoft/Boot/bootmgfw.efi.backup
-cp EFI/ubuntu/grubx64.efi EFI/Microsoft/Boot/bootmgfw.efi
