Rufus

Rufus is another very famous and easy to use bootable USB Maker. This supports all kinds of USB Pendrives, Keys, Memory Sticks, etc. The minimum software requirement is that it needs Windows XP at least.

The product page on its official website says this:

Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. It can be especially useful for cases where: you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.) you need to work on a system that doesn’t have an OS installed you need to flash a BIOS or other firmware from DOS you want to run a low-level utility Despite its small size, Rufus provides everything you need! Oh, and Rufus is fast. For instance it’s about twice as fast as UNetbootin, Universal USB Installer or Windows 7 USB download tool, on the creation of a Windows 7 USB installation drive from an ISO. It is also marginally faster on the creation of Linux bootable USB from ISOs. (1) A non exhaustive list of Rufus supported ISOs is also provided at the bottom of this page.

It supports both UEFI and GPT installations and is also open source. It is free.

First, select the ISO file, check the destination drive and all the other booting settings. Now after you pass through all the four steps by clicking next, you have your bootable pen drive ready.

Not to be biased, but I personally love PowerISO. It is fast, multipurpose and is so feature rich.
