As far as UEFI and BIOS, you can't switch between them. I have not set
the same machine up with 2 different drives, one UEFI and one BIOS
with Win 10, but I have with Win 7 - I didn't notice much if any
difference.

I'd like to know if you turn off fast boot on UEFI on Win10 is slower
to boot. I'm not concerned with Win7, BIOS doesn't have fast boot.

Elucidate for us.
