Windows 10: Multiboot system does another bios boot when selecting non-default OS Solved

    Multiboot system does another bios boot when selecting non-default OS


    Multiboot system with Windows 7 on 1st partition and Windows 10 on 2nd partition-same drive. Using the fancy blue Bootmanager Selection screen that comes with win10. Win 10 is the default OS. If I select windows 7 from the bootmanager selection screen the system does a complete bios reboot then goes directly into windows 7. Selecting windows 10 does not do this reboot, just starts win 10 as would be expected. Is this normal?? I have had Multiboot with Win 7 and XP and do not remember this happening.
    FYI
    Win7 partition is marked "Active" (first partition on drive) bootmgr file is on this drive I think
    Win10 partition is marked "Inactive" (second partition on drive)
    Tried turning off Fast Boot in Win 10 == No Help

    Any ideas?? Its annoying and time consuming to go through another complete bios boot up every time I select my Win 7 OS.
    Any help will be greatly appreciated

    Found the problem. It was the fancy new boot manager selection screen that comes with windows 10. The blue one with the different available OSs in big boxes. Going back to the original black and white Boot manager selection screen solved the problem, goes right into Windows 7 now without the extra system boot. To get back to the old B/W menu run Command Prompt Administrator and type:
    "bcdedit /set {default} bootmenupolicy legacy

    To go back to the Blue Fancy Screen type:
    "bcdedit /set {default} bootmenupolicy standard"
