Solved Can I use my old HDD with an OS with my new build? Tags: Storage Hard Drives New Build Last response: December 11, 2013 3:22 PM in Storage Share Fenomiu December 11, 2013 1:28:36 PM So yeah, basically the problem is in the heading, I'm going to build a new PC but I already have a HDD and I see no reason to buy another + an OS but I wonder if it's actually going to work. Heres a picture of what Speccy told me about my current HDD: http://www.upload.ee/image/3759522/hdd.png The motherboard I'm going to buy is this one (I added this because I wasn't sure if it's necessary or not): http://www.msi.com/product/mb/B75MA-P45.html More about : hdd build Best solution menetlaus December 11, 2013 1:37:12 PM Short answer: No (if windows) Longer answer: Maybe, but I wouldn't try it. A fresh/clean OS install is simpler than the assembly of a new PC... so why slow down a brand new system with a crud filled previous installation of an OS with drivers for completely different hardware?

Win7 oem (that you bought or came with your pc) is tied to the motherbd you installed it to and cannot be legally transferred to a new one. With Win7 retail, transferring to a new motherbd is allowed. Win8 oem or retail - transferring to a new motherbd is allowed. m 0 l Can't find your answer ? Ask !
