The tablet is NOT dual Boot, the Androind is a virtual machine, windroye.

My problem:
I upgraded to Windows 10, and since then, windroye stopped working, and I get an error message demanding to enable hardware virtualisation in bios. But when I access the bios (UEFI), there is no possibility to do that. I mention that under win8 windroye was functional, and I followed the official Microsoft way to upgrade (win8 was activated, and win10 works fine)
So:
1. Can anybody help me with this issue?
2. Any idea about a way to make my tablet dual boot?

Thank you
