Thanks for helping =) I re-read what i wrote and maybe i wasn't so clear: Both computers are almost identical; iBook and slightly newer iBook both bought within the last 2 years.

I backed up my 10.3.9 computer on an external hard drive using SD! I asked SD to erase the external first and do a full backup. I took this backup over to my other computer running 10.4.7 and told the computer to use the external HD (the backup) as the startup disk. The computer restarts, i get the grey screen with the apple on it, then i get a black screen with the cursor in the middle of the screen and that's it. Thanks for your help =)
