Additional explanations about The partition's date region doesn't...

[Vince]

         Hi,
     I have read archives of list but I must say I'm pretty confused  
with what I need to do regarding the message: The partition's data  
region doesn't occupy the entire partition. Let me explain my  
configuration. I own a Powerbook 17" 1Ghz first generation. I  
partitionned drive with Disk Utility of Tiger to get two partitions,  
first one I installed Tiger on it, and second one free. Once finished  
installation I restart with Fedora Core 4 boot CD and I start  
Installation and as soon as Keyboard setup I get the error as  
indicated above. If I switch to console mode, when I try fdisk /dev/ 
hda it complains that drive doesn't have a correct label !!
     So what do I need to do exactly to get it working and be able to  
install ?
         Thanks in advance for your clear explanations.
