Hey guys
I'm trying to update BIOS on an Alienware X51, and it's seemingly only possible via MS-DOS. But the BIOS is locked to UEFI, and there's no options to disable Secure Boot.
Any ideas to make a bootable DVD/USB with MS-DOS/FreeDOS that can be booted in an UEFI environment?
I've tried using Rufus 2.5.799 or Hiren's BootCD 15.2 (DVD and USB), but neither is bootable. Using a legit Windows 8.1 disk allows me to "click any key to boot" but then goes to BIOS right after.
Note: Rufus allows me to make a "MBR partition scheme for UEFI", but then I can't 'natively' select MS/FreeDOS. Copying files over is still not bootable. Also tried Rufus with GPT.
Any ideas?
I've toyed with the idea of using a different manufacturer's BIOS update tools that reboots the PC to DOS from within Windows, but you should never 'toy' around when it comes to BIOS updating.
