I use Kali Linux extensively when doing penetration testing and security assessments. Besides being fast, Kali Linux has pretty much every security tool I need built right in. On top of that, it’s free!
For instructor-led Windows 10 training, see our course schedule.
Another benefit, the topic of this blog, is that Kali Linux is easily installed on and run from a USB stick. Here’s how you can make your own bootable Kali Linux USB stick.
First, gather the necessary supplies. These are:
- A working PC running Windows 7 or later. I build the image from a current PC.
- A blank USB stick. It must be 8GB or larger, and should be USB 3 for speed.
- The original installation ISO from Kali.org. Do not download it from anywhere else, as you never know what you’re getting.
- Win32 Disk Imager. I always grab the most current version directly from SourceForge.
Before messing with the software I insert the USB stick in the PC and make sure it is recognized. I also remove any other USB or removable media to prevent mishaps.
Next, I fire up Win32 Disk Imager.
It’s got a lovely clean interface! Notice how it found the USB stick mounted as drive E on the right side.
Now I click the blue folder icon to the right of the Image File box. This opens a file browse window. I browse to the downloaded Kali Linux ISO and click OK.
Special note: If the ISO doesn’t appear on the file list, drop down the file type and choose *.* because, by default, Win32 Disk Imager only displays IMG files.
Now all I need to do is click Write. Win32 Disk Imager automatically formats the USB stick as bootable and copies the Kali Linux files into the proper locations.
After about 5 minutes Win32 Disk Imager announces that it’s finished. Now that USB stick can be used as a boot device (on any PC that boots to USB) to run Kali Linux.
