ya sure, you can install both the os in a single drive or on two different drives,
but the problem is if you install 2 os in a single hdd it will ask automatically to select the os to which you want to boot
but if you install 2os in 2 hdd then manually you need to select which hdd is to be booted everytime by pressing F12
