1. Switch on your computer.
2. Wait until the BIOS has finished loading, or has almost finished. (During this time you will probably see a logo of your computer manufacturer.)
3. Quickly press and hold the Shift key, which will bring up the GNU GRUB menu. (If you see the Ubuntu logo, you've missed the point where you can enter the GRUB menu.)

4. Select the line which starts with "Advanced options".

5. Select the line ending with "(recovery mode)", probably the second line, something like:

Ubuntu GNU/Linux, with Linux 3.8.0-26-generic (recovery mode)

6. Press Return and your machine will begin the boot process.

7. After a few moments, your workstation should display a menu with a number of options. One of the options (you may need to scroll down to the bottom of the list) will be "pbkg". Press Return with this option highlighted.
