How to add a second Win7 (on different partition) to BootManager menu?


Extraordinary Member
I have a "main" partition which contains my main "Win 7" system.

Occasionally I want to boot a second Win 7 from another primary partition.

When I hit at boot time <F4> I get into the Win BootManager menu.
But unfortuantely there is only my main Win7 listted.

The other Win7 is NOT listed.

How can I add it to the Win BootManager selection menu?

The bootrec /reuildBCD command is supposed to find and add other Windows installs to the BCD Store. It has to be run from the Command Prompt in the recovery environment to get access to the utility.
