Description

I recently installed Antergos onto a MicroSD card on a STCK1A8LFC and the GUI installer failed to install the UEFI partition properly and defaulted to the BIOS bootloader. Since the STCK1A8LFC only boots using UEFI mode, I needed to fix my installation.

Prepare the Partition

  • To start, make sure the system is booted up to live environment.
  • Since the installer already created the partition, but failed to assign it the proper type, run fdisk and check the type to an EFI System:
    fdisk /dev/mmcblk2
    t
    1
    1
    w
    
  • Then format the EFI partition to FAT32:
    mkfs.fat -F32 /dev/mmcblk2p1
    

Install Grub UEFI

  • Mount the system partition that contains /boot :
    mount /dev/mmcblk2p2 /mnt
    
  • Mount the EFI partition:
    mkdir /mnt/boot/efi
    mount /dev/mmcblk2p1 /mnt/boot/efi
    
  • Install grub efi:
    grub-install --target=x86_64-efi --efi-directory=/mnt/boot/efi --boot-directory=/mnt/boot --removable --recheck
    
  • Unmount and reboot:
    umount /mnt/boot/efi
    umount /mnt/boot
    reboot
    h2. Resources
