    Grub error 15

    I'm trying to install unbuntu on a partition of my thinkpad T410.

    I created a USB with the live image 64-bit amd. The problem is that when I use the USB to boot, I get:
    GRUB loading
    stage 1.5

    error 15

    And that's where everything stops. I tried two different images:
    ubuntu-12.04.2-desktop-amd64
    and
    ubuntu-13.04-desktop-amd64

    There are other ideas on here with this error, but they involve a started installation. This won't even go forward.

    What about installing Ubuntu via CD/DVD?

    I don't actually have a CD handy and nothing's open tomorrow.

    Do you think this would make a difference?

    I think you should give it a try, and maybe you should try the 32-Bit versions too. But I don't know what's wrong with your laptop, I just wanted to tell you that you didn't try everything.

    Why would booting from a usb create a GRUB error?

    The usb just has the ubuntu image on it.

    Re: Grub error 15

    How old is system? How much RAM?

    Grub error 15 is from grub legacy. Did you have an old install on system as Ubuntu has not used grub legacy since 9.10, although if you had an old install you could keep the old boot loader.
    So it seems grub2 never fully installed.

    If older system 32 bit Lubuntu may be better choice. But my laptop is 6 years old and does run the 64 bit full Ubuntu but I do not use Unity as that requires more graphics power than old system really has.

    You can download Boot-Repair into your live installer or download the repairCD version which can also be on a flash drive. If your system boots flash drives that is usually a better way to install. A bit quicker and flash drive is then reuseable.

    The laptop only has Windows 7 on one partition. The other partition has not been formatted yet. The USB key has the ubuntu image on it.

    The system is not that old. It's running an Intel Core i7 CPU @2.67GHz, 4GB of RAM.

    I've checked the BIOS and there's nothing there.. and there was no previous GRUB on the system.

    Live installer should not have grub legacy.

    Download Boot-Repair into live version or download the secure remix as it is an installer with Boot-Repair already installed. For newer systems and flash drive install.
