Windows 10: Dual Booting with windows 10

I have both windows 7 and 8 installed and reboot to switch from one to the other. If I upgraded one of the windows installations to windows 10; will it affect the installation of the other? In other words, will I still be able to dual boot?

I'm worried that if I upgrade my windows 7 to 10 it might identify and remove my windows 8.1 as well.

Integrated Bluetooth module stopped working

You could setup Windows 10 in VirtualBox and use it there or dual boot:

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.
