I am trying to remove the F12 boot options from a Dell Optiplex 790 machine. We have other models in our environment as well that I need to do this on. I just want to boot from the Hard drive. However, using the CCTK tool, I am not able to disable the "onboard or USB CD-ROM" boot option that appears after hitting F12. Does anybody have any experience with the CCTK or might be able to shed some insight on how to do this? I have tried tinkering with a lot of the settings in the CCTK tool but no luck.
Note...i can get this to work if i disable the CD-rom in the BIOS, but when the user logs on they will not be able to access the CD-rom drive. When i hit F12 during POST, i just want the Hard drive to be listed only.
