IGEL UDC Installation stays in a gray screen forever


Trying to flash some Dell Optiplex 390 desktops with UD3 10.04.100 or 10.05.800, but can’t. After it boots from thumb drive, I select UDC Installation, and it stays in a gray screen forever. I’ve tried diff thumb drives and other desktops of same model. Any one have any ideas?

Are there any secure settings configured in the BIOS possibly that would prevent installing a different OS?


Not that I could tell. I tried installing using Verbose Mode and it is constantly saying “failed to load module nvme”


Any chance there is a BIOS update for those devices? I know Dell had a lot of fixes are NVME stuff in their BIOS updates over the past few months.


A coworker formated another USB thumb drive with the preparestick utility, and now I’m able to flash a desktop. I used Rufus before.


Those dang USB prep modules – it’s always a crapshoot, and you’re left to second guess the results. Not your fault, just know your pain. Brutal.
