A few days ago I had to repair my wife’s laptop, and I think it would be easier to repair the BSOD by reinstalling the Windows. I had no DVD, so I must create a USB installer. Then, I found a great tool called Rufus.Rufus is a small tool to create a bootable USB installer, not only for Windows, it also supports Linux, you can install Debian, Red Hat, CentOS and many other distros. For Windows XP fans, Rufus is not suitable for you, sorry. 🙁
The best things that I love from Rufus are: fast, super simple, and portable.
No installation guide, I think. Just download and run it, then load you ISO file from your hard drive.
Download the latest Rufus from here.
