UEFI Booting Optiplex 9020 issues
What am I doing wrong here. I'm trying to UEFI boot a new Optiplex 9020 from USB but when I select the the UEFI Boot USB device it just flashes and returns to the menu.
When I try to boot a new Latitude E5450 UEFI - I get 'Operating System Loader signature not found in secureboot database'.
My K2K boot environment was created from WinPE3 and I downloaded the USB flash drive image (x64) and installed on a flash drive using the FAT32/UEFI option to format/install. I then tried creating a new boot environment with WinPE5 and the same results. I can boot Legacy with the same boot environments on USB formatted NTFS.
Thanks. Russ

Booting to UEFI USB has been fixed. The problem was actually two issues. 1. The WinPE-5 file I was using was old so it didn't have everything needed to create the KBE. Downloaded the newest file. 2. McAfee was causing things to fail even though I had built at least 15 KBE prior without having issues. Gotta love McAfee. Disabled it and he KBE was finished without issues. And it worked.

We are just getting into the whole UEFI thing. I have been successful at booting a 7020 with UEFI. Sounds like you solved your problem. - jboling 9 years ago
