    Also, if you set the bootmenupolicy to Standard on the Windows 7 bootloader,
    Boot should fail (if set) as loader parameters are handed over to ntoskrnl.exe.
    Win 7 kernel does NOT know about bootmenupolicy as this was introduced later for Win8.

    So using the Windows 8 boot manager (bootmgr), would not make a difference?

    Give it a try and you would know (try W7 loader, bootmenupolicy=0 and bootmenupolicy=1).
    It has no meaning having W7 bootmgr on active if W8 is installed as W7 bootmgr cannot load W8.

    Did you ever wonder why I made the statement in the first place?

    How many bootmgr files do you show on your system? This thread is about a very specific configuration.

    Hello Boyans.


    I'm not trying to be hard to get along with, just curious, with Windows 8 on an Extended partition, you're saying it's still handling the boot in this case?

    Win8 can display a text menu, or what you are calling the GUI menu.

    Text menu is not "old". It is the best for multibooting - that is why it is there.

    The GUI has big squares - for touch screens .

    If you are multibooting, text menu is vastly better. If you only have a touchscreen - GUI is much easier to operate.

    The drawback to the gui is that if you select anything apart from win8 - your machine will reboot.

    Yes, you are using win8 bootmgr.

    Yes, it is safe... and run it from within Windows 8 so it will use that BCD store.

    It seems others cannot duplicate your situation. I seem to have no trouble duplicating it. Since you have confirmed the other suggestions, such as set Win 8 as default and have bootmenupolicy set as Standard, and it has not fixed your system, the Bcdboot command will work And I even get to keep the F8 options, but only from the text boot menu.

    If you have doubts, use the bcdedit /export C:\TangoBCD.bcd so you will have the old version you can go back to if you were to feel the need.
