Boot problem ROG STRIX Z390-F Gaming

[Ulfh2022]

I suppose this is not not the right forum, but if so, can someone please tell me where to go?
Have had Windows 10 up and running on this motherboard, but installed an update from Asus, which changed some settings so I could not install Ubuntu on another drive. Had to reset back to AHCI, and then my windows installation got corrupt, so I tried to reinstall. Problem is that windows installation crash each time while booting the installation USB. I suppose this might be a BIOS setting, but I have absolutely no idea what it can be. Have tried to reset BIOS, but did not help.
Any idea who I could ask?

Best regards
Ulf H
