Ubuntu won't boot with Windows7

I installed Ubuntu 12.04 LTS on a hard drive, and after that on a different partition on the same hard drive with windows7. In both cases, after Ubuntu finished installing, the computer reboots, and it boots automatic into window7, without any boot menu to select the OS. So, How can I make my bootloader to see both windows and Ubuntu?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

The GRUB Bootloader is missing. Follow these steps to reinstall GRUB.

  1. Make a new Ubuntu live CD and boot from it.
  2. Install boot-repair using these commands:

    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update
    sudo apt-get install -y boot-repair
    boot-repair

  3. Click “Recommended repair”. This will reinstall GRUB in the adequate disk(s). Then reboot.

Solution 2

Did you use a USB to install Ubuntu? A common problem recently is that grub has been installed to the USB drive, and Ubuntu will not boot without booting the USB, so test that.
If this is the case then have a look at our guide on re-installing grub.

Have a look at this page on our website for more details.

Note: Use and implement solution 1 because this method fully tested our system.
