If it's stuck at the text, then

A) It'll go through a bunch of things right at the start, then stop for a few minutes, then start repeating the same few lines every few minutes thereafter. The last thing it prints before it stops is the important part.

B) My guess is the last thing will be something related to the sd card, i.e. mmcblk0: p1 < p5 >. If it is this, the easiest choice is to repartition the sd card. Use the HP Disk Tool (I believe it's linked in the first page -- otherwise, google it).
