I know nothing about Windows, but as far as I can see the documentation could actually refer to select the option that talks about a CD. Attached is my QEMU.cfg. Yours might need to be different. Specially, I make sure to add the GuixSD image as a USB storage device — using the sections `[drive "stick"]', `[device "xhci"]' and also the `driver = "usb-storage"' in the lone `[device]' section. I also make sure to add the internal storage as the first drive, perhaps this is the issue with your command. Anyways, the configuration file attached can be read using something like this: ----------------------------------------------------------------------- [Prefered qemu-system command] -smp 1 -readconfig [Configuration file] ----------------------------------------------------------------------- I used `-smp 1' in the command line anyways because I don't know a way to tell that same thing in the configuration file.
