I've tried numerous ways to access the boot menu for my Acer TravelMate P249 N16Q1 laptop.
I've smashed the F12 button for days on boot up. No dice.
When I run the Advanced Startup and choose the EFI USB Device or EFI DVD/CDROM choices, the device tells me System doesn't have any [CD/DVD/USB] boot option. Please select another boot option in Boot Manager Menu.
But the Boot Manager does not have any other options other than standard boot from the hard drive.
My purpose is to wipe the hard drive using DBAN from a bootable device. I can then reinstall Windows for a clean platform.
