Cannot boot into Seven after installing Build 9926
After installing Windows 10 build 9926 tonight in a dual boot set up with Seven, I can no longer access Seven at all. When I select to boot into Seven, all I get is a black screen.
When I force a restart I get a pointless disk check that finds no new errors (a bad 4kb sector shows up, but that is old).
I can sometimes get to the Windows Seven startup repair/restore screen, but running either of them does not seem to fix the problem.
I can usually get into Ten (like I am now), but even then I have issues... like my mouse will not work about half of the time.
I really need to get my Seven back... and no, a re-installation of Seven is not in the picture.
How do I fix this mess?
Edit: It looks like my boot sector has been moved from C:/ Seven to Y:/ Ten... and I don't know where that F:/ partition came from!
