I installed Fedora 7.0 the other day. You want to set aside a few (3 at least) partitions for Fedora. The main partition for the OS, Swap partition (make this about double the amount of RAM you have), and the boot partition (only needs to be like 100mb

).
With what your friend was talking about, it's possible he may have just been talking about the partitions. During the Fedora install you need to setup partitions and junk, and it's possible for you to delete them all, leaving you with no usable space on your HDD, until you make partitions again.
Just a word of warning, when I installed Fedora, I think i messed something up, as it managed to delete all my NTFS partitions, rendering my Windows useless. Thankfully I'd just installed it as I was doing a clean install of everything.
Installing:
While I can't give you step by step instructions, I can give you directions for the first few steps.
First things first, obtain a copy of the .iso file. And ISO file is like a direct copy of a CD or dvd or whatever, but in a single file. When you rip a dvd to your computer (or the way I do it at least) it is saved as an iso file, this singular file can then be burnt to a dvd.
Once you have the iso file, you need a program that can burn images. Personally I use
ImgBurn. It's a nice free image burning program. I use it for burning my dvd iso's. Just so you know, i've never attempted to burn a bootable ISO thing from ImgBurn, I have done so from
InfraRecorder though and it worked perfectly fine.
Next, boot up your computer and enter the BIOS (usually you have to mash the del button while the computer is starting up) and change the boot order to make CD/DVD before the HDD. Put in your dvd and save/restart. A Fedora boot screen should come up. Select to install. it's really quite simple if you know what it's talking about.
