Currently running windows 10 pro x64 on two 250gb Samsung 850 pros and just installed my 750 a couple days ago and op checks fine for now.

I downloaded the windows 10 OS from Microsoft onto a USB and ready to wipe and install in UEFI

My only question is, if i back up my C drive and restore to the 750..would there be any conflicts by chance with my currently installed windows ten and the one i downloaded once im up and running again?
