I've downloaded Fedora 3 under Windows and i've used Nero to burn to a DVD. I then rebooted with my drive as first boot, unfortunately it just booted straight into Suse (which i want to overwrite).
When Suse had booted i found the ISO and clicked it expecting to find an installer or something, but it justs opens K3B as if i wanted to burn again.
How do i get it to install??? I've previously bought Mandrake and Suse (Mandrake is on my serial ATA and is my favorite distro, Suse on my IDE which is my playing with drive), and both of them just booted straight from the disk, have i done something wrong or missed something.

Please help!

You have to burn the ISO file to DVD using the 'Burn Image' function. It does not help creating a data DVD with the file on it.
