Does anyone know of a way to remove entries from the boot device menu when you hit F12 on your keyboard. I need to implement this at work for security reasons so no one can boot from a CD-rom or USB device. I want the CD-rom and USB entries removed from the boot device menu. See attached picture.
notes..the PC is a Dell Optiplex 780 PC
Things I tried:
1. Disabled CD-rom drive from BIOS and this works, however, when the user logs on there will be no Cd-rom drive showing.
2. Boot from hard drive as first option, and implement a bios password to prevent unauthorized users from booting to CD-rom drive or changing the boot order. However, if they reset the BIOS/CMOS jumper than they will be able to gain access to the BIOS again.
3. Tried using Dell CCTK tool but it doesn't seem to be removing the CD-rom entry.
4. Disabled F12, F2 options but although it doesn't show up during the POST, you can still hit the F12 key and the boot device menu will show up.
Out of ideas so I am trying this forum. Thanks in advance.
