Yesterday I installed a new faster harddrive to replace my old one. This morning, after I cloned it, I went to disconnect the old one and my PC wouldn't boot. Now, if I put back in my old one, it still won't boot. SOMETIMES windows will load but it'll randomly flash on the page before the login page. I have Windows 10, what can I do to fix this besides just wiping my harddrives? It would really take a long time to reinstall everything and some files would be lost. Thanks!
