Under each machine’s config page there is “Power boot type” option
Oh my, I never saw that option before! Unfortunately, I didn’t receive a notification from this forum that you replied and I ended up doing a manual install of the server and it’s already in production now. So, it may be a while before I’m able to confirm whether the solution could be as simple as switching this option from “Automatic” to “EFI Boot”…
Thanks… I bet this will solve it!
As a side note, I tested this with MAAS 3.2, and MAAS 3.3 and both failed at detecting that the machine was only capable of UEFI boot.
