[Leaplist] Install Fedora Core 8

[William H. Ferguson]

Ladies and Gentlemen:L

I  installed Fedora Core 8 on a brand new computer with a 500 GB hard 
Drive. The Hard Drive was new and virginal and has never had any Op. 
system installed on it previously.

I  FAILED  to successfully CUSTOM Partition the Hard Drive and Logical 
Volume Extended Primary Partition 4.

So I gave up and chose the "Default" Installation which the Installation 
Screen says is
           "Good for most users."

I have since learned a little bit about Custom Installation and went 
back to try again.
That is, I booted up again with the DVD Fedora Core 8 Installation Disk 
in its drive and the Installation program starts right up.

But each time I try to set up a new Partition, regardless of the size I 
choose for the new Partition,  the program tells me on the screen that 
it can't create a Partition of the size I have chosen, even if I reduce 
the size to 1 Megabyte!

So, I conclude that since I have installed the "Default Partitioning" 
all of the Hard Drive's
space has been taken up by that choice.

My question is:  How can I clean everything off the Hard Drive, now 
apparently jam-packed full of the Default Installation?

I want to be able to start over and attempt the Custom Partitioning 
Installation again.
Please tech me how to clean off the Hard Drive so I can attempt Custom 
Partitioning again.

Thank you for any guidance.
