My current PC is running windows 7 and i wanted to try out windows 10 on my Pc before i upgrade. Im currently using a 3tb hdd on my pc and because i use it as the boot disc windows 7 will only allow me to allocate up to like 2.2tb. So i have like 740gb that is unallocated and i wanted to know if i could use that un allocated space to put windows 10 on it and run it as a dual boot.

Thanks in advance to anyone who helps
