Having read that Windows 10 & 2012 were running hapily on APU devices, and wanting to build an MS AD Lab (i'm more a Linux guy, but a man has to learn), I decided to give it a try.
Hence I took an old laptop (running Legacy BIOS and not UEFI, in case of), and installed W2016 on it.
After a couple of reboot, so basics settings seemed to be ok, I took of the SATA HDD drive from the laptop, and put it in the APU.
I went into the BIOS and configured it to boot on SATA 1st (not America) instead of mSATA.
It said "Booting from HDD" (or something like this), and just rebooted, continuously.
Did I miss something? Should I have installed it in UEFI mode?
Thanks for your support & help :)
