For all with this situation, there is a workaround: Boot your ubuntu and install grub to the linux partion "grub-install /dev/sda6 --force" in my case (you need --force, because grub will tell you, that install grub to a partion is not the nice way.
Boot your windows - with supergrubdisk - or by Windows Disc in repair mode and bootrec.exe install a tool "EasyBCD" - now you can add the linux partion with grub in it to the menu (chage the default one, time, etc.) - if you used Supergrubdisk you have to install the windows bootloader to the MBR. EasyBCD can do this (WinXP bootloader/Win7 bootloader) - Win7 Bootloader in my case what will this do ... the 1. bootloader will be the Win one. In my case, it will boot by default linux. Win bootloader will load grub ... and than ubuntu. BTW: after this ... and a update-grub ... win7 sillt won't boot out of grub BTW2: I used Supergrub2disk 1.98s1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/704515 Title: Windows won't boot anymore -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
