    You can do a start-up repair using the W8 DVD, if none use the W7 DVD.
    Sometimes one will have to do this 2x!

    Get a small program called EasyBCD
    add the proper for you your Windows 8.
    mine 3x boot reads as follows:
    Windows 7 Ult (C:\Windows)
    Windows 8 Pro (F:\Windows)
    Windows 8 Ent (G:\Windows)

    save then reboot an you will have options to chose:

    to get back win 8 boot loader:
    Run command prompt (SHIFT+F10) from the Windows 8 installation medium.
    bootrec /fixmbr - update the main boot record
    bootrec /fixboot - update the boot sector of the system partition.
    bootrec /scanos - add known OSes to the boot configuration data
    bootrec /rebuildbcd -rebuild the boot configuration data.

    I have the same dual boot with win 7 and win8 with EasyBCD(Great tool by the way).
    When I start up get my boot screen with win 7 and win8 start win 7 and shutdown everything went fine.
    When I choose Win 8 also boot normal, but when I shutdown Win 8 with the shutdown button (on the right side of the screen), and start again I get no bootloader screen.
    I only get the normal bootloader screen when I choose the Restart button.
    I readed somewhere that the shutdown in Win 8 is some kind of hybernate, to startup quicker ???

    greets from Holland ;)

    UPDATE :
    Found the settings in powercontrol now It boots both OS
