Double check BIOS boot priority.
After you manage to install both operating systems, I highly doubt they will let you choose which one to boot. If you get no choice to boot from, then I suggest installing GRUB to manage boot stuff.
I also doubt if cloning stuff you mentioned would work for you. Yes, machine should boot that way, but if you want to test them, then you need them in perfect working order, which you would not get if during installation and after hardware would be different.
