This is exactly what I was thinking about last night! I have an extra 1TB Nvme stick, so I formatted that and ONLY used that in the Nvme slot. I also have a bootable USB drive that I have Windows11 installed on. With the USB and the Nvme stick installed.... I booted into bios. There I killed legacy mode/rom and enable UEFI and secure boot. It all looked great in the beginning. I was able to start in UEFI mode, Windows 11 was starting to install then the only place to install it was the USB, and it won't install on that. My 1TB Nvme stick was no where to be found.
If I can get a way to have that stick show up I have a feeling all should work
