I have recently purchased a 256GB Samsung 750 EVO SSD. I want to install my copy of Windows 10 on my SSD. I don't have a physical copy of Windows 10 and I haven't been successful in cloning since I'm taking it from a 1TB HDD that is almost full ti a 256GB SSD and I have no extra HDD to back-up my HDD. Will it work if I install my copy of Windows 7 with the disk and then use my key for Windows 10 that I was given when I upgraded to Windows 10 to upgrade to Windows 10?
