Thread: Dual Boot problems

    Default Dual Boot problems

    After restore of Windows partition Boot manager of Grub2 is no more present.

    Now using RescaTux/SuperGrub i make boot and find Grub2 configuration on
    hd0 msdos7 /boot/grub/grub.cfg
    So Grub2 start correctly in dual boot on Windows 7 or Linux.

    Now to restore old setting I'm logged on OpenSuse 13.1.
    grub2-mkconfig -o /boot/grub2/grub.cfg
    don't change boot manager

    Using autorepair of Rescatux see grub2.cfg on sda7 and configure it on sda, but don't start GRUB2.

    After I have probed configure using yust2 bootloader after boot via SuperGrub.
    Setting on 'mbr' grub2 at startup compare but as prompt and don't start.
    I have proved also to set /dev/sda7 for grub position but don't start.

    Using Grub Customizer work correct to change grub2 settings, but don't start.
    I have also probed to install GRUB and not GRUB2, it work but don't start.

    After then i hare restored Windows mbr.
    To start with OpenSuse I have to start using SuperGrub.

    That command rebuilds "grub.cfg", but it does not reinstall grub2.

    I'm not sure I understand that.

    When I last tried to reinstall grub using Yast, it did not actually install. So I had to use:

    Code:
    # grub2-install --force /dev/sda1
    Installing on "/dev/sda7" probably won't help you, because that's likely not a bootable partition anyway. It could work if you copy that to a boot file to add to Windows boot manager, or if you rewrite it to the extended partition and mark the extended partition as active.

    At this point, I'm not sure what you are wanting to do.
