    In following: "Grub location"

    =>place Grub in "sda4"


    To Reinstall Grub

    You need to have Ubuntu Live CD or Live USB. Normal session can be used to repair the grub. Boot using your Ubuntu Live CD or Live USB, while booting choose Try Ubuntu.
    Once booted then open a terminal, and run the following command one by one to install the boot repair.
    To add boot-repair to the repository
    $ sudo add-apt-repository ppa:yannubuntu/boot-repairTo Update your repository
    $ sudo apt-get updateTo install boot-repair
    $ sudo apt-get install -y boot-repairOnce Installation complete run boot-repair on terminal by typing the following command or select it by System->Aministration->Boot Repair.
    $ boot-repairNOTE: Update the Boot Repair if its newer version is available.
    It will scan the System for few seconds and will show you the options Recommended repair and Create a BootInfo summary. By clicking the Recommended Repair it will start repair the grub. Check the screen shots below.


    Once done click ok and restart your system, your grub should work now. If not run the boot-repair again using live cd / usb. Then follow the steps below.
    Select the Advanced options, In Main options tab check whether the following options are selected or not. If not select it, the options are Reinstall Grub and unhide boot menu for 10 seconds. Check the screen shot below
    Then select the GRUB locations tab and check the following options are selected or not. The options are OS to boot by default and place grub into, In “OS to boot by default” option choose the OS which you want to be default on boot. Then select the drive where you need to reinstall the grub in “place grub into” option and click apply. Check the screen shots below

    exit
    D: is not active anymore in disk management now? Try to boot in win7 and ubuntu. Works?
    D: already marked inactive?
    Do you have a "win7 system repair disk", "win7 install dvd" or any live CD that can mark partitions active/inactive?

    I just went to msconfig to check that all my cores were enabled and there is NO boot entry there so I can't access anything on the boot tab (See attachment)
    What can I do about this please.

    Andy

    I appreciate your help and time, but I must now ask if rebuilding my grub is going to help with the original problem, since I am able to select windows and ubuntu from the grub menu without any problems, I do suspect my grub to interfere with the proper functioning of msconfig in windows, but only because I read it does that in several forums, but rebuilding it is something I would rather avoid unless it can be confirmed as the reason for msconfig not to function properly or task manager not reporting all the cores in my processor

    once again thank you very much for all your help

    Alright no rebuilding yet.
    In win7 elevated command prompt:

    Code:
    bcdedit/enum  all
    bcdedit/store c:\boot\bcd /enum all
    attrib c:\boot\bcd
    Which command fails?

    ======================
    Looks fine as well. Don't why but seen it before... it's because you boot to grub! That's why msconfig and bcdedit aren't working.

    Bootsequence is now: sdb (MBR)->sda4 (grub bootmenu)->(sdb1 [win7] or sda4 [linux])

    Only sda connected to system... boot fails
    Only sdb connected to system... boot fails

    Not a real problem as long as both are connected.

    What do you want to change using msconfig btw? You can't do "bootmenu" stuff now (boot tab).
    But you can do it using:
    bcdedit/store c:\boot\bcd .....
