Trouble installing QubesOS from USB

I don’t get any sort of output, not even to my windows

If you connect the first display in nvidia GPU and second display in intel GPU then will you have video output on second display in Windows?
What’s your motherboard?

My motherboard is an MSI Z490-A pro, and no I only get output from nvidia

Try this:

I’ve already tried that haha, still didnt work

You can try to disable the Nvidia GPU in Qubes OS so it’ll use Intel GPU instead but I’m not sure if it’ll help.
You can try to add module_blacklist=nouveau kernel command line option in Qubes OS GRUB menu like this:

But I’m not sure if it’ll fully disable the Nvidia GPU.
To fully disable the GPU you may need to mount the Qubes OS dom0 root partition in another OS and edit the configs like this:

There was this report that the problem was caused by some other PCI device:

But I’m not sure if you have the same problem.

Can you access the console on another tty?
Did you try this?

If you can then you can disable the Nvidia GPU there without mounting the Qubes OS dom0 root in another system.
