I have an HP micro tower PC with dual core AMD 64. This pc has a problem in recognising it's cdrom drive. As a result I need to choose another medium to install the OS from. I have gone to the Fedora 7 mirror sites and copied the /os directory contents want to boot and install from that usb stick which has been formatted to ext3. It's failing to detect os. How do I structure the files and directories in that USB stick !
