The thread quoted in the first line deals with rendering bootable again my main Windows 7 working partition on HD-0 or at least recovering its user data. In the line of action followed there I finally deleted the 100 MiB partition checking the "Clear Boot Sector" option.

The present thread shall help me to make bootable again the Win7_Koy partition on HD-1 (the one newly installed for upgrading to Win10).
I have already tried in vain several consecutive runs of WinRE. BIBM says the partition is bootable. BIBM can also resize it without changing its size. But when I tried to boot the "resized" partition I got a black screen with the message "This partition does not contain an Operating System. If you are about to install a new OS then insert the installation diskette into drive A:
Press any key to run the BIOS bootstrap loader..."
When I open "BCD Edit" I get "No BCD store"
I WOULD LIKE TO POSE TWO QUESTIONS:
QUESTION 1
Maybe I will resort to restoring the full backup I have made of HD-0 just after deleting the 100 MiB without checking anything. This backup would give me the opportunity to undelete the 100 MiB. My question is whether I can restore the backup over the existing HD-0 without prior deletion of the data contained there.
QUESTION 2
How can I find and position the correct BCD that would boot the partition? I would prefer this course of action to restoring the full HD-0 backup.
