Create bootable USB from ISO image with Rufus

If you want to reinstall operating system on your PC or laptop, you can install it from USB flash drive which is very easy and faster compare with optical drive like CD, or DVD.

Last time, I wrote an article about how to create bootable USB with UNetbootin which is a good tool, but there might be some issue with large image file (NTFS file system). So I’m going to recommend another tool which works great and have no problem . It is Rufus.

Rufus is a free software (GNU GPLv3) that can format and create bootable USB flash drives. It can create USB installation media from bootable ISOs (Windows, Linux, UEFI, Hiren’s, etc.). It works only on Windows, but you can use it to create any bootable operating system. It also has full support on UEFI and GPT.

Requirement

  1. ISO image file (Windows, Linux, etc).
  2. An USB flash drive

In this article, I will show how to make my USB flash drive, SanDisk Cruzer Fit (8 GB), bootable using Windows 8.1 installation ISO image with Rufus.
