I've just dual booted Windows 7 and Ubuntu, but whenever I boot my computer the grub loader asking me which OS I want to boot into doesn't appear and I get launched straight into Windows. I installed Windows First, and they're on the same HDD, on consecutive partitions.

Any help appreciated, Matt

Try to show the Grub menu

Hold down the Shift key as the computer attempts to boot to display the GRUB 2 menu. In certain circumstances, if holding the Shift key method does not display the menu pressing the Esc key repeatedly may display the menu.

If that doesn't work, then Grub somehow got removed or corrupted. Use Boot Repair to reinstall and fix it.

Boot Repair

Live CD

First, you'll need to boot from a Ubuntu Live CD.

Repair the bootloader

To restore the Grub bootloader, follow these steps.

Open a terminal from the Live CD, and run the following commands:

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

After a few seconds, Boot Repair's main window will open.

Click on Recommended repair.

You're done!

Reboot to test everything out.

If everything went well, you should be up and running by now.
