So i just got a Samsung SSD 850 EVO 120GB SSD, and I want to set it up as a boot drive and use my 1 TB HDD as my storage drive. Only a couple of things i had questions about. My boot disk is windows 8.1 and windows 10 is what's on my HDD. Will those have any conflict? Also when I put Windows 8.1 (OEM disk version) will Windows allow me to use the same key since i used it once before? Also does anyone know a really good guide for this because all the ones I found are pretty crap. Any help is appreciated
