Having issues switching to legacy boot mode on a ES1-533 Acer laptop I am trying to troubleshoot. 
I have set a supervisor password in order to unlock the option to disable secure boot, disabled secure boot, saved and exited the "bios", re-entered the bios to find that it is still hard set to UEFI boot mode still and I am still not able to change it. There is also a secure boot mode option under security I am not able to select. I even tried setting a user password and hard drive password for ***** and giggles. There is nothing in the online manual pertaining to this from what I can see. Anyone have any experience with this one?

EDIT: I should also mention that I am attempting to boot from a bootable USB flash drive formatted non-UEFI(MBR) that contains various utilities. Usually I can just disable secure boot, enable legacy boot mode, boot from the drive and do my thing and then go back and change back the settings in the bios.
