   1. Boot the machine.
   1. During the BIOS screen, press the shift key and hold it down. You should see the GRUB menu after the BIOS loads.
   1. Navigate to the kernel entry you want to boot, and press 'e'.
-  1. Then remove the '''quiet''' and '''splash''' keywords (found in the line starting with linux).
-  1. Starting with Natty (Ubuntu 11.04), also remove the parameter '''vt.handoff=7''', and on the line that reads '''set gfxpayload=$linux_gfx_mode''', replace with '''set gfxpayload=text'''

  It's best if you can attach a log file which may have captured any messages you see. If you are unable to capture a log file, a digital photo will work just as well. As a last resort you can even copy messages down by hand.
  
- Depending on the type of error messages you encounter, there are other boot options you could try. For example, if you notice ACPI errors, try booting with the '''acpi=off''' boot option. For a full description of these options, refer to the [[http://www.kernel.org/doc/Documentation/kernel-parameters.txt|kernel parameters]] document.
