I have an all-in-one Model D18WS Z24-890-UA91
I want to boot from a thumb drive. I restart holding the DELETE key, get to the BIOS SETUP UTILITY, screen, select BOOT OPTION:
1. select REMOVABLE DEVICE OPTION => select F10 SAVE AND EXIT, does not work, I get a regular windows boot.
2. As above but I highlight REMOVABLE DEVICE OPTION which moves this option as the only item showing,, hit F10, does not work, regular windows boot.
3. As 2 except after highlighting REMOVABLE DEVICE OPTION I hit F8 SAVE AS USERDEFINED, then hit F10 SAVE AND EXIT. Again, does not work, I get a regular windows boot.
What am I doing wrong?
