    Press SHIFT key at startup. GRUB2 Menu will appear. Note down entry number of other OS.
    Let say, other OS is appearing at line 3 in GRUB Menu. Counting of GRUB Menu entries start from zero. It means you have to set default value to 2.
    Open /etc/default/grub file and set GRUB_DEFAULT value to 2.
    Code:
    GRUB_DEFAULT=2
    Save file and execute sudo update-grub command to generate new GRUB Menu.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Hey Devils;

    So I managed to get into the GRUB (finally eh?), and I have run into another issue (go figure...). The GRUB only lists three things: Ubuntu, Ubuntu recovery mode, and Memory tests (note: there's two of each, but they are almost the same thing???), it does not list my Other OS. Should I reinstall Win 7? Is there a chance it will erase Ubuntu, or cause damage to ubuntu? I do need Win 7 for school, as I require some of the features (IIS 7, etc), however I really want to use Ubuntu as well. So is reinstalling Win 7 going to provide it as an option in the GRUB?

    Also; I just wanted to thank you for all your help, I never would have gotten this far without you, and you have been more than amazing. Thank you very much for everything you've done for me so far, and I hope in the future I can find a way to repay you.

    Thanks much,

    Dustin<>

    The multiple entries for Ubuntu are probably different kernels if you've done an update. If the kernel number entries are not exactly the same, that is what it is.

    I would not suggest you re-install windows 7. If you do, it will overwrite your master boot record and you will be back to where you are now and will need to re-install Grub.

    I don't use Ubuntu or Grub2 so the best I can suggest is this link, a Grub2 tutorial. Section 5:C should explain dual booting with windows 7.

    GRUB2 should detect Windows OS without any problem. Lets check partition structure of your Hard disk first.
    Open Terminal and execute this
    Code:
    sudo fdisk -l
    Post output here.

    * It's a small L in fdisk -l.

    Did you resize Windows 7 partition before Linux installation? Windows 7 partition should be first Primary Partition but it's a second partition in your machine.
    Execute sudo update-grub command again. Does it list Windows 7 while detect OSes?
