Out of ideas... I used DriveCopy 12 like a champ to migrate Windows 8 to my SSD, and would run the OS from the SSD and use the old drive as storage. All was well until 8.1, which got boinked. I re-copied the SSD over and over, and it will not boot. It says successful, I can see it in the BIOS, I can see it in the disk manager. But it will not boot. I bought another drive, and I get the same result. All shows it worked, and I can see all the files, but 8.1 simply will not boot up my system (8 worked fine). Any ideas?? I'm at my wits end... UPDATE Screwing around in the BIOS, I changed something about the SATA controller (n00b alert), and it gave me an error on reboot about BOOTMNGR missing. Reset the controller and booted to the legacy drive and that worked, but no SSD. Make any sense?
