I have two drives a WD Black and a 500GB Seagate. For some dumb reason Windows 8 installed its boot stuff onto that Seagate. I found by accident by removing the Seagate drive and failing to boot win8. Can I somehow fix the installation I have on the Black drive or do I need to reinstall? I ran the repair from Win8 volume but it reported I have Windows 7 on that black HDD...must be the old installation.
