How to change boot order without using BIOS
I have Ubuntu 16.04 on my acer computer and I'd like to change the boot order but I forgot the password....I want to boot my USB Drive first (with windows).
I found some topics about that but when I type 'efibootmgr' in a terminal, I get this :efibootmgr: EFI variables are not supported on this system.
Can you help me please ?

The error message may be caused by booting the USB in legacy mode instead of UEFI mode. How it boots -- legacy/UEFI is set in the UEFI settings/BIOS...
