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
