Are you only using QEMU, or are you using some sort of wrapper around it? QEMU is quite advanced, if you aren’t already, I’d recommend you use some sort of GUI like virt-manager or something.
Can you share your config?
Does it BSOD or just reboot after the Windows logo?
You might have to pass the drives through as IDE, Windows might not have the proper drivers for anything else. Once you can get it booting you can mount a blank drive as virtio, install the virtio drivers, and then change the OS drive to virtio.
