Usage:
run_archiso [options]
Options:
-b set boot type to 'bios' (default)
-b set boot type to 'BIOS' (default)
-h print help
-i [image] image to boot into
-s use secure boot (only relevant when using UEFI)
-u set boot type to 'uefi'
-s use Secure Boot (only relevant when using UEFI)
-u set boot type to 'UEFI'
Example:
Run an image using UEFI:
$ run_archiso -u -i archiso-2020.05.23-x86_64.iso
