    No boot manager on windows 10 new install


    Can someone please help me? I am running windows 7 as my primary os and decided to try windows 10 on its own hard disk. The installation was successful but I can't get into windows 7 now unless I force boot in the bios. The funny thing is that the windows 10 hard disk is labeled as boot manager in the bios but there is no boot manager option available. Could someone walk me through the fix for this? I really don't want to reinstall again.

    Sorry if this is a repost, but I'd really appreciate the help.
    Thanks

    I found a solution by using the bootrec /rebuildbcd command. Booted off the win 10 cd, repair pc option, command prompt...

    The only thing funny is when I choose windows 7, the pc re boots again completely before it loads os making another delay, but hey it works. Thought I'd share..

    I`m guessing you didn`t unplug the W7 drive before you installed W10 ??

    If you had then you could just use the boot menu to choose either OS, keeping them completely separate.
