Installing help

[Daniel Makman]

Hi I want to install Unbuntu 7.10 on my Mac. If i install Unbuntu,  
will it over write Leopard. I want to know if I can partition my hard  
drive to install Unbuntu on the partitioned side. I'm to nervous to  
start from the CD I burned, and click install because it might over  
write all of my data if i click it does it give me the option to write  
on a partition or create a partition through the install menu.
