    Add Boot Option After Win 8 Install?


    I've seen all the tips on setting up a dual boot while installing Win 8 with an existing win 7 installation but I can't find any way to add a boot option AFTER installing win 8.
    I have an image of win 7 that I want to put on another hard drive and then be able to dual boot either 8 or 7.
    I tried using easybcd and it appeared to save the entry but it wasn't there when I booted up.
    On a side note I also can't seem to change the timeout value before it boots. It always reverts to 30 seconds. Any ideas? I tried msconfig with the same results.

    I do have an added boot menu for a recovery via Farstone recovery. It added it to the win 8 boot menu so it must be possible to add the win 7 somehow.

    Thanks

    Is your Windows 8 installation on UEFI/GPT ?

    I have already experienced situations (even on BIOS/MBR) that you have to restart Windows 8 so changes to BCD are permanent.
    Windows 8 has to be shut down completely, which means fast startup (new in Win8) must be disabled !

    And what OS you are booted into will make a difference. If EasyBCD is not sticking, you may be booting to another BCD Store.

    Edit: I will have to do some more research in the command.

    I currently just use the Boot Device Menu to switch between OSes...

    tried full power down (even unplugged it) with no change.
    easybcd shows save as successful but the new entry does not show up. It's still the win 8 GUI menu and I need to get back to the win 7 text interface I think.

    I booted into recovery and used bootrec to rebuild the mbr and it found the installation and I was successful in adding it to the menu.
    Thanks guys for the ideas!
