Verifying the Download in Linux

Once you have downloaded BackTrack, you should check the validity of the downloaded file using md5sum. For example:

BackTrack 5

BackTrack 5 has not yet been released, this is a placeholder.

BackTrack 4

root@bt:~# md5sum bt4-r2.iso 
9a94caa0e980a7331e9abc1d4c42c9a9  bt4-r2.iso
root@bt:~# 

• BT4-R2 ISO md5sum: 9a94caa0e980a7331e9abc1d4c42c9a9
• BT4-R2 VMware Image md5sum: 95c8b727d01b96b6df84381065cd9da6

Verifying the Download in Windows

download and install hashcalc from

SlavaSoft HashCalc - Hash, CRC, and HMAC Calculator

Its a free tool

Open hashcalc Uncheck all the checkboxes except md5

Change data format to file

In the data box on the right hand side is a button with 3 dots, click it and navigate to where you downloaded your .iso or .bz2 and select it, click open.

Now press calculate

After a few seconds (or more depending on your computer speed) there will be a string next to the word md5, this is the md5 of your file.

Compare your md5 to the md5 hash on the download page.

If they are the same then your iso or bz2 is good, if not your file is corrupt and you need to download it again.

Verifying the Download in OSX

Open up the Console and type md5 and a space, then drag 'n' drop the image to the Console window.

Press enter and wait.

Then you should see an output something like this:

MD5 (~/Downloads/bt4-r2.iso) = 9a94caa0e980a7331e9abc1d4c42c9a9

Important note

Please remember that the most common problems arise from either a md5sum mismatch and in the case of a DVD, burning too fast, using low quality media or burning the iso as a file instead of as a disc image.


What next?

The ISO image is bootable, meaning that you will need to either burn the iso to a DVD or transfer it to a USB stick. Once you have done this, you will then be able to boot your computer into the BackTrack Live environment. From this Live environment you can continue to use BackTrack or install it to your HDD using one of the installation guides listed on the Installation page.
