========================
Detailed description：I would like to boot my laptop from either a CD-ROM or a USB device but it is impossible: the list of bootable devices (in the ASUS Bios manager) does not include either one. The CD-ROM is included among the storage devices but not in the bootable devices list.
I have tried to disable the secure boot but nothing has changed.
