Hi,
Qubes 4.0 rc4 is the only OS on the machine right now. I don't use Windows!
Set SATA to ACHI
Set Legacy Boot node
Got "soft lockup - CPU#0 stuck for 23s!" messages and loop.
At the blue GRUB(I think?) screen, hit tab and added modprobe.blacklist=nouveau
Installation completed successfully.
So far, only spent about an hour testing.
WIFI works,
Video(intel GPU) and sound work.
Startup and Shutdown work fine.
The HiDPI screen renders everything very small, been working on scaling the desktop.
