Dual boot licensing, Win 10 x64 + Win 10 x64

I would like to install two instances of Win 10 Pro x64 on one computer and run dual boot. How many licenses are required?

 

How do I restore dual boot capability after Windows 10 clean install removed it

My computer was dual-boot with Windows 7 boot partitions on two separate drives. After upgrading to Windows 10, the dual boot provision worked fine. However after a clean install of Windows 10, dual-boot capability is no longer available. The boot partition
for the remaining Windows 7 syBistem is intact. Only the dual boot option is gone.

I tried the changing the default operating system under System Properties/Advanced/Startup and Recovery, but the only choice is Windows 10. Windows 7 isn't a option. I'm guessing that the clean Windows 10 install wiped out access to the dual-boot menu.

Thanks.
