Okay, so I have a question. I've got a PC with windows 10, and I've got a 120GB hdd as the one that has the OS and everything. I want to replace it with a 1TB hdd (I already have 3 other 1TB hdds in the PC). How can I manage this, without losing all my windows settings, or tweaks or such? I assume I can't just copy all the data to the other drive and boot from it like normal? What's my best option, short of re-doing windows installation all over again?
