Re: Booting physically installed Windows while in Arch (AHCI support in OVMF?)

Bump.

I'm currently in such a state I won't be able to sleep well before I
make some progress on this.
I've already described my situation quite precisly, if one needs even
more information, just ask.

I've now also tried with a separate img containing DUET, so I can use
the default seabios to boot DUET, which can  boot Windows in UEFI
mode. However, DUET just doesn't see my disk at all, be it in IDE or
AHCI mode. If I boot the same img *physically* (from a usb), I can
enter DUET and I can see my physical disk (which is running in AHCI
mode). So I guess this is an issue with KVM/QEMU.

Any ideas would be greatly appreciated.
