+Usage:
+ run_archiso [options]

+Options:
+ -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'
+
+Example:
+ Run an image using UEFI:
+ $ run_archiso -u -i archiso-2020.05.23-x86_64.iso
