i downloaded Fedora 12 iso file. how can i create a bookable disc from an iso file and install
Please suggest me how to install Fedora 12 in a machine ?
Try using a Fedora-specific tool for creating live USB drives - Fedora Media Writer (Windows/Mac/Linux). Fedora Media Writer (formerly Fedora Live USB Creator) is a free and opensource tool for easily installing live operating systems onto USB flash drives.
Well on windows, you can use imageburn to burn the iso into a cd. If you have linux, brasero and k3b do the same thing. remember that you want a cd with the iso contents, not a cd with the iso in it.
Alternately assuming you have a USB key and the image is of a livecd, you can use unetbootin or rufus to make a bootable usb to do the install
Oh, and for god's sake, RTFA. I believe fedora should have a guide on how to install it.
