Hi, yesterday i received my new hard drive, i tried cloning with easeUS todo backup but failed to boot(""Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key"), then i tried with easeUS partition master, but that failed to clone. Then i tried with seagate discwizard. It failed to clone as well (most likely due different format on hackintosh partition) so i deleted the hackintosh partition and rebooted, then it said "missing bootmgr" so i decided to make a clean install on the new drive, from an USB. Everything worked as should, i got all my files copied while i was installing drivers, then after installing graphics drivers i rebooted. Then i got a message reading "operating system missing" I rebooted, then i got a message reading "Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key" after that i reattached my old drive and it offered me to boot onto the operating systems on it but not on the fresh one.
