Step 1 – Download DBAN
First, download the latest DBAN version from its official site. DBAN is available as an iSO file so it can be burned on CD or USB. So it won’t open directly after download. You can download it on any computer. It is not mandatory to download on the computer you want to erase completely.
Step 2 – Burn DBAN to CD or USB
Now, to use DBAN, you have to burn the ISO file to USB or CD. This process is a little tricky as it cannot be burned just like other files. You can use a special tool that will unpack the ISO and burn it on the CD or USB. You can use “Free ISO Burner” for CD and “ISO to USB” for USB. But keep in mind that creating a bootable USB drive will erase everything on it. So make sure you don’t lose data on the USB.
Step 3 – Remove all the external storage drive from the PC
Remove all the removable drives from the PC such as USB flash drives, optional internal hard drive. This is for more security. However, DBAN will let you select the drives you want to wipe but this is for safety.
Step 4 – Boot from the CD or USB
First, insert the boot CD and restart the PC. If everything is right then you will see the blue DBAN screen. If it doesn’t work for you that way then restart the computer again. While startup looks in the corner of the screen for F12 = Boot Menu or F11 or any other things, depending on the manufacturer of the device. If you don’t press that key on time, you have to restart the system again.
If any of these doesn’t work for you then you have to change the boot order in the BIOS. So, now you have to enter into the BIOS setup menu. While rebooting the device you have to press any particular key to get into the BIOS setup. They can be DEL, F1, F2, or ESC depending on the manufacturer. Once you are in the BIOS, you shall have to change the boot order from the CD before the hard disk. This can be a little tricky so you can get help from YouTube or any of your expert friends.

Here, by highlighting the drive you have to select the erase and press SPACE key and you shall see “wipe” word in the selection box. If you see more drives than you have selected then you have to restart the PC again ensure the one you have selected is in the selection box. So, remove all the external drives from the PC from accidental erasure.
Step 7 – Start the wipe process
Now, press F10 key and the process of wiping will start. You can see the percentage of completion on the screen. The time of completion depends on how occupied the drive is.
Step 8 – Finale
Once everything has gone according to the plan, you shall see a “pass” sign in green highlight. Now you can remove the boot CD and turn off the computer. If there was any problem in the process then you will see the word “ERROR” in red. So you have to repeat the process.
