Installing OSX 10.4.2

I have a powerbook g4 with OSX 10.3.4. My boyfriend just got a new powerbook with OSX 10.4.2. I tried upgrading my OSX and it keeps saying that it can't install. I even backed up everything and did a clean install of my old 10.3.4 and tried to install the 10.4.2. Any suggestions or reasons?
I'm fairly new to macs so please be patient if I am asking something stupid.
 
You can't use the optical disk that shipped with your boyfriend's new PowerBook. That disk is specific to his computer model and will not work on your model. You need the retail version of MacOS X 10.4 to upgrade your old system. You can then update to MacOS X 10.4.3 via Software Update.
 
Ah, I thought maybe something like that might be a reason it wouldn't install. I guess I have to shell out the money for the upgrade.

Thank you!
