I'm actually attempting to convert my windows install into a VM these past few days, it's most of the way there now, just need to get the VM to actually boot from that drive.
It was my original intent upon switching to Linux that I would VM my windows, however only in the last few days of trying (read: failing) to get mods for a few games working under proton, that I've really upped my effort.
If there are any resources you recommend, I'm all ears.
I'm not sure this will help, though I'll suggest anyway that you poke around looking for (I hope I got this right) "rkdevtool", I believe you can get it from somewhere in the Orangepi tools, I found it while looking into putting orangepi os (droid) onto it.
Do let me know how you go, I have a copy if you can't find it that I'm happy to share. I haven't yet tried it so I can't speak to whether or not it works.
