    Ubuntu 10.10 can't dual boot to windows 7

    Few hours ago I installed ubuntu for the first time on this laptop.
    Everything went fine, fixed some stuff. So I wanted to go back to windows 7 for a while. Since I where in ubuntu I restarded my laptop and waited for the dual boot to show up, so I could chose between Ubuntu and Windows 7.
    Clicked enter on Windows 7 and the screen went black for 2 seconds and putted me back to the dual boot screen. Clicked Windows 7 again, and it sent me back to the dual boot screen again. This is really confusing, can't figure out what is wrong. (the last thing i recall doing is making windows 7 the first priority in booting up. So when I turn on my computer the dual boot will open windows 7 at the beginning.)

    The Grub loader over-writes the Windows MBR. You can repair it with a Windows repair cd, sometimes by running the "repair my computer" 3 times. If that doesn't work there are several other options so don't worry too much

    Is your bios set up to boot from the cd drive first? If not set it that way. Then put the Windows cd in the drive and boot up the pc. You may be asked to press a key to boot from the cd and you may be asked to press the R key for the recovery console, do that.
    When the recovery environment appears select "repair my computer". It will then search for Windows operating systems. It may not find one the first 2 times you run it. On the third try it should find the Windows system and ask you if you want to add it to the boot record. Answer Y for yes, then reboot if it runs ok.
    If this option does not pick up the system click on "next" or "advanced options" and select "command prompt" option. Then in the command prompt type
    Code:
    bootrec.exe /fixmbr
    and press enter
    there is a space in between exe and /fixmbr.
    After it runs type
    Code:
    bootrec.exe /fixboot
    and hit enter (same space)
    After it runs reboot and the Windows 7 entry in the grub menu should now boot Windows.

    Edit: ill try a windows xp cd
    It actually detected already the Windows 7 entery. But when i went to dual boot it still did not run windows 7 and my windows 7 cd doesn't have recovery console.

    What happens when you run the cd? If it's a Windows cd (and not a recovery cd) it should have recovery tools, as far as I know. If not there are websites which offer the cd for download.

    For W2K and XP, boot with the Windows CD, enter the Recovery Console, run fixmbr.

    For Vista and Windows 7, boot with the Windows disk, enter the Recovery Environment, run Bootrec.exe /FixMbr.

    Sometimes, you also need to reset the active partition.

    Run that 3 times and see if the third time it is different.

    You need to go to "Commend Prompt".

    And then refer to my first post.
