With my case it definitely is the Active partition. How do I know? I set the Win8 partition to Active because it was not the active one and I should have known better. When I rebooted I got the blue screen of death.
No going back, So I booted from my Win8 disk and tried the repair feature. Did nothing.
So I selected install and the option to keep my files. It almost looked like it might work when I got the message to reboot to finalize the update to 8.1.
So I rebooted and still got the blue screen. Win was not clever enough to re-establish the boot files on the active drive. It was a loop.
I finally had to recognize that I lost the gamble and needed to re-install Win8 from scratch with everything else. I am more than pis#@d.
To add insult to injury, now I do not even get the choice in the Win8 store to upgrade to 8.1. So I am stuck again, worse than before.
What gives...
