Accessing BIOS Toshiba Satellite

Hello,
I just tested it to enter the BIOS on a Toshiba Satellite:
- Press F12 and the power button
- the BOOT MENU page appears
- on this page (at the bottom of the page) choose "Setup utilities"
- You enter a schematic BIOS.... which allows you to choose the desired boot type:
- for example, I was able to modify it for the PC to boot from a USB stick, here is the link that explains the modifications to be made:

( this link explains that you need to modify 2 THINGS in BIOS: "Set the 'Secure Boot' option to 'disabled' and the 'UEFI Boot' option to 'CSM Boot' in order to allow the system to boot from an external device").

I hope this will help someone
Good luck to all!
