Arch & UEFI [Was: Bug on missing staging modules rpm]

[Alonzo Cuellar]

Hello Janina,

Sorry for the long responce again.

Doing

bootctl install coppies the needed files in /boot/loader and /boot/EFI. 
It also adds an entry in the efi menu to boot the kernel.

the file

/boot/loader/entries/arch.conf tells the system to simply boot the 
kernel as you described previously in one of your messages.

blkid -s PARTUUID -o value/dev/sdxx will get your PARTUUID. This should be the PARTUUID of your 
root partition which for me is /dev/sda2. /dev/sda1 = EFI and is mounted 
on /boot /dev/sda2 = my root partition and is the partition you want to 
get the PARTUUID value /dev/sda3 = home The partition table has to be in 
gpt. The ESP (EFI system Partition) is in fat32 I've not used 
"efibootmgr" so I can not currently comment on that. It took me a while 
to get an EFI system working a few years ago. Now that it works... Its 
probably the easiest way of booting the system. For me anyways. Note- 
You will need to have secure boot turned off for Arch Linux. You can 
have the system installed successfully. However, if you have secure boot 
enabled Arch will not boot. I hope this clears up most things. Alonzo
