    Unhappy Trying to dual boot Win7 & Ubuntu 12.04 on Gigabyte H77 - boots straight to Windows

    Goal: to dual boot Windows 7 and Ubuntu 12.04 (both 64-bit) from a single hard-drive with a Gigabyte ga-h77m-d3h Motherboard.

    Problem: After installing Windows 7 and then Ubuntu from USB without error, the machine boots straight back to Windows - not showing any boot-loader.

    The Ubuntu live USB continues to work.

    I have tried wiping and installing a number of ways: the automatic 'install alongside windows' option as well as specifying the partitions manually.

    Using EasyBCD did not work for me.



    Perhaps is could be something to do with my 'BIOS'? The mobo came with '3D Bios - Dual UEFI'; I don't pretend to know much about UEFI but I've read that it can cause some issues when dual booting.

    When I look at the boot order with the liveUSB inserted, there is a UEFI label with the device.




    I don't know what to try next. There isn't any data on the computer, just the operating systems so I don't mind reinstalling (again) if I have to.


    Any and all help is much appreciated!!

    Yes, UEFI makes big difference.

    For UEFI you need to install ubuntu in uefi mode too, in other words, boot the usb stick in uefi, not the standard mode. You said in the boot menu there is uefi label with the device, use that.

    For windows or ubuntu to be installed in uefi they need to be booted in uefi mode.

    I'm not sure if that's enough for it to work, because there are other issues with uefi too, but that's a start.

    Thanks for your reply!

    When I said there's a UEFI label above the usb stick in the BIOS boot order menu, I meant that I can't see any alternative.
    The only thing that shows up is that and my harddrive.

    I'll delete the current Ubuntu partitions and try and see if I can boot it in some other way I guess?

    Would I need to do the Windows side as well or would that've installed in UEFI mode automatically?

    Could the way the startup USB is created somehow affects if it boots in UEFI mode or not?


    Sorry, I don't understand this stuff too well.

    The cd you can boot in both modes, about usb I'm not sure if it depends how it was created. I don't use uefi and don't have many details except few things mentioned here on the forum.

    Windows should have installed in uefi automatically if uefi is enabled on the board. You can test also if you boot the ubuntu usb in live mode (doesn't matter uefi or not), and in terminal execute:
    [code]sudo parted -l[/code+

    If it says the partition table on the hdd is GPT, then windows is in UEFI because it can only work with gpt on uefi. Otherwise, it works with msdos table in the standard bios boot mode.

    You actually might be OK with the way you've set up. In my ASUS UEFI BIOS, there is an option to boot the USB device either in BIOS mode or UEFI mode. Perhaps you don't get that option in your BIOS and boot into UEFI by default?

    The best thing to do would be to run the "Create Bootinfo Summary" portion of the Boot Repair package:

    https://help.ubuntu.com/community/Boot-Repair

    With that we can have a look to see how Windows is setup and what the boot partition looks like. It might be a simple matter of configuring Grub to pick up the slack. Please post the results of the Bootinfo Summary here with code tags and we'll see if you need to reinstall or if you're already OK.

    Well I just reinstalled Ubuntu again after confirming the USB was booting in UEFI mode (I still can't find anywhere to control if it does or not).

    Still boots right into Windows.

    Here's the output:

    ubuntu@ubuntu:~$ sudo parted -l
    Model: ATA WDC WD5000AAKX-2 (scsi)
    Disk /dev/sda: 500GB
    Sector size (logical/physical): 512B/512B
    Partition Table: msdos

    Number Start End Size Type File system Flags
    1 1049kB 106MB 105MB primary ntfs boot
    2 106MB 74.1GB 74.0GB primary ntfs
    3 74.1GB 500GB 426GB extended
    5 74.1GB 492GB 418GB logical ext4
    6 492GB 500GB 8478MB logical linux-swap(v1)


    Model: Kingston DataTraveler G3 (scsi)

    Partition Table: msdos

    Number Start End Size Type File system Flags

    So partition table is MSDOS, what now?

    By the way, the windows installation was done from a startup USB created by 'Universal USB Installer' using a Windows 7 Ultimate ISO.

    Thanks for your reply, I'll look into this now.

    In that case you are not using uefi, since windows needs gpt for uefi.

    If possible, try to disable uefi in your BIOS.

    Try running the boot-repair suggested, it should understand the setup and do everything for you.

    Will do.

    Like I said before, I don't have any data on this computer yet (I just built it yesterday).
    If there's some way to reinstall windows using UEFI, I can do that if it's easier...

    Here's the Bootinfo summary: http://paste.ubuntu.com/1172001/

    I guess I'll try running a repair.
