Ok so a few months ago I bought the Asus G75 gaming laptop. Originally it came with 2 750 GB hard drives and Windows 8 as the OS. I replaced those two hard drives with a 512 GB Samsung SSD and a 120 GB Samsung SSD. I still have the original hard drives that came out of the laptop sitting in the SSD boxes in my closet, but I was wondering if I could use them in my desktop. I have ordered the 2.5 to 3.5 dual mounting bracket for my tower, but is it possible to hook them up and run both Windows 7 and Windows 8 on the same PC? I just dont want two perfectly good drives going to waste. Especially when they have a legit copy of Winsows 8 I paid for on them. If someone could give me step by step instructions on how to do this it would be greatly appreciated! When I say STEP BY STEP I mean STEP BY STEP lol! I am good with some aspects of computer parts and installation, but this is way out of my league. Thank you!
