Hello, I've recently built my parents a new computer. I assumed that I could just take the harddrive out of their old computer with Windows 10 on it and install it in the new. I didn't know it was motherboard bound so when I booted up on the new computer it said Windows not activated. So I downgraded to Windows 7 and some Windows files got corrupt yada yada I eventually got it to boot in to Windows. I'm going to buy them an SSD and a new copy of Windows, could I use their old harddrive as mass storage? Also how would I transfer all their data from the old harddrive to the SSD or atleast delete Windows off the old HDD. Thanks!
