USB boot setup in Bios
Dell XPS12 (No internal CD/DVD drive)
Am trying to backup my Primary SSD to an external SSD. Have not been able to succesfsully
configure the BIOS to allow a boot from a bootable USB pen drive.
Can anyone provide detailed steps on how to setup to boot up from the USB pen drive?
Thanks
Ron

Either the pen drive needs to be set up as GPT (NOT FAT32), or you need to boot into legacy mode (secure boot off) if it's not.
On this model, disabling UEFI and enabling legacy boot turns off secure boot and will allow a pen drive to appear as a boot device. However, once you're done, you MUST change the setting back again or Windows won't boot from the internal SSD.
F2 at powerup to get to the BIOS to change the settings.
