Mounting a DVD and / or CD image(s) onto a hard drive...

Linux Distribution: Fedora Core 5
Problem: No DVD-R(or W) drive and a loss of CD-R availibility
Description:
I recently downloaded a Live-CD of a Linux Distro that was used to help get me back on my wireless network. I want to mount a DVD or multiple CD images onto a extra hard drive I have (3.43 GB, ATA 66) and want to mount it onto it. But unfortunately, I searched the Internet for answers and got nata, nothing, zip, zero on the topic. I currently don't have any money to go and get new CD-R(or W)'s or get a DVD-+R and DVD-+R's. How would I mount the image so it boots from the hard drive and installs on another hard drive (the setup should let me do this)?

Secondly, while I'm on the subject, how do I mount the flash drive image (diskboot.img in images) onto my flash drive? Can I boot the installation on the flash drive and let a network share on a Windows 2003 server with the image availiable install it on the remote computer?

Lastly, how would you get a portable hard drive to boot a Windows disk like it was a CD / DVD?

I only have Windows XP Professional Workstations and 2K3 Servers. This topic was posted in the Linux section, but didn't give me the results I needed. Please help.
