I recently tried to install a Samsung 860 evo 250gb but on migrating Windows over using their cloning software it wood not boot. I tried this multiple times but had the same issue. I then thought it was probably something to do with it migrating so did a fresh install but still had the same outcome. I even swapped the drive incase it was faulty. Motherboard is an Asus rog maximus VI and current ssd is a Sandisk plus 60gb which is still working fine. Does any one have any ideas on solving the issue? Thanks
