    Unhappy Urgent help required

    My laptop had windows operating system already, I installed ubuntu 10.04 . I restarted my laptop. Now boot screen isn't coming. Only windows is getting loaded. How to fix the MBR using windows? Windows forums are useless. So I posted this query here.

    Re: Urgent help required

    Perhaps you didn't install GRUB on the MBR when you installed? You should be able to boot Ubuntu off the install CD and rerun GRUB from there.

    Re: Urgent help required

    are you getting grub menu if you hold the Shift key while booting ? If yes then boot into Ubuntu and change boot time to 10 sec By using Grub Customizer .

    If no grub menu then post the output of bootinfoscript .

    Look at my signature for both the things.
    All the best.
    Dont miss anything even it is small. one small pin is enough to bring down a man.

    is it related to sda9?

    you are going to have to load a live cd
    then look at this link Post #2
    http://ubuntuforums.org/showthread.php?t=1851164


    as I see from that great boot script that ubuntu is installed on

    sda9

    Try to install grub to it again. Let us know how it works out.
