Microsoft USB/DVD tool is very easy to use, you need 4GB flash drive and original untouched ISO image. You can obtain them for now from MSDN, Technet and some other places, just make sure to check the SHA of the ISO file.
If you do not want to the USB tools (or can't use them because your removable drive shows up as a
local disk) it is possible to make a bootable USB drive with only the Windows 8 ISO and a working Windows machine.

The Microsoft USB/DVD tool does not work on some systems. So I used the following tool to create a bootable Windows 8 USB drive. This tool can be used to create only bootable USB drives, not a DVD.
