Hello everyone,
I'm experiencing a strange issue with a windows 11 UEFI VM: basically, any option to boot from the network via PXE has disappeared from the UEFI bios and boot manager.
The option is simply completely not available anymore, and I can't seem to find any place either on the webUI or the UEFI firmware to reenable it (if possible).
I don't know if it has anything to do with windows 11 and its latest updates (?), can an OS update actually disable something in the UEFI?
The VM has secure boot and TPM enabled to work with windows 11 properly.
I've attached 2 screenshots of the UEFI firmware of the affected VM as well as another one to show the differences.
Also the PXE options are not available as devices to add in the boot order from the device manager.
A bunch of options also seem to no longer be available.
I've also noted that the firmware version in the win11 affected machine is 4.2025.02-3, which is newer then the other one that is 4.2023.08-4
Is there a way to restore the missing functionality?
EDIT: Sorry, my bad, the problem was already discussed previously in the forum but my keyword search didn't hit.
Adding the virtioRNG device solved the problem.
