Hello Qubes OS forum community,
I have bought a Dell XPS 8940 PC with i7-11700 CPU.
I prepared an USB stick with Rufus in Windows 10 with MBR and after that with GPT boot scheme.
I can:
- Use UEFI (Dell Recovery check after boot from USB stick.
- Deactivate UEFI (Boots but hang up after text loads before the actual installer).
I can’t:
- activate the legacy mode (not possible anymore on newer UEFI/BIOS settings.
Error (UEFI deactivated / no legacy mode (not available) [MBR/GPT scheme nearly the same]:

=> After that I can’t do anything (hung up) except hard reset.
=> Is there a solution available where I don’t require the legacy mode anymore?
=> Any clues?
