I had an idea that I could create a USB stick with Windows Boot Manager which would boot Windows installation from SATA. Created a bootable USB stick using bcdboot and bcdedit tools but it doesn't boot from AHCI and shows error that "boot device is not present" but the same stick works for legacy IDE booting. Seems even Windows 10 boot manager doesn't boot AHCI.

Maybe some 3rd party boot managers/loaders support AHCI boot like GRUB2,GRUB4DOS, PLOP which could be run from SARDU?
