    Talking [solved] I can't boot windows after installing ubuntu (SOLVED THANKS TO DARKOD)

    If you are having a similar issue I suggest you read through this thread to make sure you have the same issue as I did. Throughout the thread there are two working solutions; one that requires a win7 repair disk and one that can all be done from the linux terminal.

    Thanks to darkod I was pointed to this link which fixed my problem in a very easy step by step manner.

    MY ORIGINAL POST:
    Hi,

    I'm currently dual booting windows and linux.
    When i first installed ubuntu (after windows 7) everything worked fine except I accidentally installed the boot files to my usb flash drive for ubuntu,
    The only way i could boot ubuntu was to push f10 while my pc was starting up and select boot from my usb drive.
    So i started the process of trying to get a grub menu when my pc powered on.
    Now i got my grub working but the menu never popped up. So I used the repair tool and now a grub menu appears. However, it wont display a windows partition!
    Here is the URL the repair tool gave me.

    I need to be able to boot windows. I'm hoping I didn't somehow delete my boot partition.

    Re: I can't boot windows after installing ubuntu

    Tried run grub-update?
    On startup, hold SHIFT from when you see the BIOS load screen to bring the GRUB menu up.
    To make GRUB show at booot: http://askubuntu.com/questions/87409.../106706#106706

    Re: I can't boot windows after installing ubuntu

    I've tried update-grub. I already got the grub menu to display using the repair-tool. So that isn't my issue. My issue is that in the grub menu there is no windows boot. only 2 ubuntu option and a previous ubuntu version option.

    Just trying to track down the issue so that I can ask the question or search forums for the right topic: Is there a way to verify that my windows 7 boot is still intact? Or is that part of the results you had me post above?

    If my windows 7 boot is still intact I won't need a recovery disk, correct?

    and if it's not this is going to be much more complicated?

    I've been browsing forums but I'm scared to try things because I dont want to mess my system up worst.

    Run update-grub, then use the solution I linked to get the GRUB menu appear at boot.
