    Windows 8.1/10 Enterprise x64

    No boot menu on dual boot WIn8.1↔10


    HIYAS
    I have installed Win10 on secondary partition while keeping Windows 8.1 as primary. Everything went fine, after few reboots Win 10 was ready to use. After setting up things I rebooted, In boot manager I have two entries
    - Windows 10 as default
    - Windows 8.1
    I choose more choices, change booting default and select Windows 8.1, then back to boot menu. Windows 8.1 take first place, I select it and boot. After closing Windows 8.1 session I reboot and await the boot menu but ooooooooops, there's none . Something had to go wrong. I used Paragon HDM advanced recovery CD to autorepair boot issues but apparently without any effect, boot menu missing. Now I don't know how to selectively boot to Windows 10.
    Thanks for any advice how to restore my Windows boot menu (with Windows 8.1 as default).

    Are you booting into 8.1 without any problem?

    Yeah no problems with Win8, except that on boot screen the wheel is missing (cosmetic issue) and no boot menu at all.

    Greatest solution would be flexible 3rd party UEFI boot manager as Windows BCD has been always obscure, hardly repairable and hardly maintainable.

    Try assigning a drive letter to your 10 partition. If you used D, for instance, you would enter the following command in an elevated prompt to create the boot files:

    Code:
    bcdboot D:\Windows
    Opening msconfig from a run command will give you the option of viewing the boot entries and choosing a default.

    Edit: Is there a reason your 10 partition doesn't have a drive letter assigned to it?

    So no

    bcdboot U:\Windows

    finished success, but the only effect is that boot wheel animation shows up again now. Boot menu skipped though.
