You can use geteltorito AUR to create bootable USB images from the Bootable CD: Tip: There are unofficial firmware available, such as Coreboot or Heads in order to remove hardware whitelists and provide trusted boot.Īll official updates, including Windows utility, Bootable CD and documentation can be found here. Small ESP (100 MiB fat32) also supported. X230 in UEFI-non-CSM mode installed with EFISTUB on SSD disk boots into display manager in less than 25 seconds. Though you can delete any boot variable, so be careful! UEFI boot options can be safely (no bricking) set with efibootmgr or UEFI Shell v2 (checked with BIOS 2.77 (G2ETB7WW) EC 1.15).
