Comment 1 for bug 635065

Hi,
  I don't know French, so this is based on a google translation!
I think what you should do is bring up the grub boot menu by pressing shift just after the bios and then edit the boot commands
(I think it is e to edit) and remove the

quiet splash

from the kernel line.

then boot using ctrl-x

It will probably still hang, but hopefully the screen might have more information to explain the problem that you can add to this bug report.
