I believe that the fault lies in the Win 7 BCD. I have this Win 7 / Win 10 Pro with BIBM working perfectly on my desktop computers (three of them), but when I use BIBM to look at the BCDs, all 3 of the desktops have completely different entries than the laptop. Unlike the others, the only entry in Win 7's BCD is a "Resume" entry, with no main boot entry at all! I tried deleting it (using BIBM) then creating one that matches one of the desktop's exactly, which worked exactly ONCE before it was mysteriously replaced with another "resume" entry again (I'm lookin at you, Microsoft!

On the other hand, my manually created entry may have been deleted because the GUID I copied from a desktop BCD might not have been correct for the laptop. Anyone know how I'm supposed to determine the correct GUIDs to use for a particular BCD entry?
Anyway, how do I fix this troubling problem? And ideally make the horrific Win 10 boot manager go away or at least remain invisible?
Thanks!
