Hi - I upgraded because I wanted to implement Secure Boot on Windows 8.
However, that is another issue. It is impossible to enable Secure Boot on the OptiPlex 9010 with the ATI video cards (same as purchased via Dell). What happens is that when I enable secure boot, and then enable the option to disable legacy drivers, I can no longer see the boot screen when the system boots up.
If I remove my video card adapters, I can boot fine with the onboard Intel graphics; however, if I add back in my ATI video cards it will fail.
Is this a known issue?
Will this be fixed via a firmware update to the ATI Video Cards?
