i want fedora but i don't know were to install it from so please can some one help me step by step how to do it please

You download the ISO CD or DVD images, burn them to CD/DVD and then boot from the first CD or the DVD to start installation. If you're having problems, tell us what they are.

I suggest you look at the link below (Getting Started....)

I agree with all that has been explained above. I wonder if you have the CD / DVD already. I have a DVD of Fedora 7 that you are welcome to have for free if you email me your address. My email address is turnerconst@hotmail.com. If you have downloaded the image you must burn it as an iso file. That means regular CD burning software will not work. You must use something like Nero or go to Linux Puppy website and download their free iso burning software for Windows. If you have the CDs / DVD in the CDROM and when you restart you computer and Windows comes up, that means your Bios aren't set to start from your CDROM first. To start the installation of most Linux Operating Systems (assuming you are not doing an network install or some other out of the ordinary installation) you must "boot" from your CDROM. To reset your Bios to boot from the CDROM first you must push a key or combination of keys as your computer starts up. That will bring you to some screens one of which will say something like "boot order." Set it to boot CDROM, Floppy, C and save the changes and exit and you are in business. Put Fedora in your CDROM Restart and follow the on screen instructions. Good Luck.
