I've replaced my intel i5 with an amd ryzen 7. Now my Windows 10 VM (libvirt/qemu) won't boot, it just shows "preparing automatic repair" and then reboots.

I cannot boot from a rescue iso either. I do have EFI shell access, and can access the file system through a loopback. How can I get my system to boot correctly again?

I was able to boot by switching the cpu from host-model to qemu-64.

Performance seems fine, so I'll leave it like this unless I find a way to boot with host-model.
