partitioning

[Renato Pedroso Henriques]

For a newby this is quite an issue. you know that.

I have a power mac g4, power pc platform and I already had ubuntu 
installed but now I wish to do something with your help. I have one 
disk with 2 mac hfs+ partitions. One partition is empty and the other 
one is where the mac os X system is installed. May I use the empty 
partition to install ubuntu power pc but leaving the mac partition 
intact?

There is no graphic installer with the ubuntu installer cd that I have 
so it is much more dificult when I get to the manual partition part.

Thanks,
Renato
