I would like to use a flash drive to make backups of the machine. I have run into an issue though. I cannot make the bios skip a flash drive if it has no boot content. it still tries to start from the flash drive and then gets stuck. I would change the boot order, but I also plan to include another flash drive that can be booted from, that will restore the original image without user intervention. Is there something I am missing to make this work? My fallback plan is to use an SD card to store the backups, but I prefer to use a flash drive. That way a non-tech at a remote site could insert it easily into a new unit if one had to be sent out.
PS- This is on an APU2.
