How this technically works:

1. Insert the same disk image into both SD card and VirtIO HDD
2. UEFI recognizes VirtIO and boots from it
3. Windows does not see VirtIO but does see SD card
4. UEFI did not recognized SD card, so it only reported one HDD controller to the OS
5. Windows does not go mad and proceeds to boot

Tested Windows on ARM builds:

• ✔️ Windows RT 8.1 - build 6.3.9600.17328.armfre.winblue_r3.140827-1500
• ✔️ Windows 10 Enterprise - build 10.0.15035.0.woafre.rs2_release.170209-1535
• ❌ Windows RT beta - build 6.2.8330.0.armfre.fbl_woa.120424-2227

Known issues:

• Keyboard will not work in UEFI
• UEFI only can boot from VirtIO, but we're doing a trick here
• USB EHCI emulation is not perfect and may get broken, especially during installation
• Works only on 1 CPU core, it's possible to add more, but they are not being detected
