The following should be done on a computer other than the one you are planning to wipe.
One time preparation
- Download the following files:
- Insert a USB flash drive. This drive may be wiped, so make sure there is nothing on it.
- Under Step 1, select DBAN from the long list under the heading ‘Other distros alphabetical’
- Under Step 2, click Browse and select the
dban-2.3.0_i586.isofile you downloaded
- Under Step 3, select the USB flash drive you inserted from the drop down list. Check the box that says ‘Fat32 Format Drive’
- Your screen should have the same options as the one below. Click the Create button.
- A few screens will pop-up. Once everything has finished, you should see a “Process is Complete” window like this:
- Insert the USB flash disk you prepared.
- Make sure the computer you want to wipe is completely turned off — a restart from within Windows may not be sufficient.
- Start up the computer. During the initial boot screen, you need to get into the boot menu or the BIOS. The computer likely displays the key you need to press to do this during that first boot. It is probably something like
F12. Press these buttons repeatedly during the boot to try to get into BIOS or the the boot menu.
- Note: If Windows starts to boot, you are past the boot menu. Press the reset button and try again (you don’t need to let Windows finishing loading).
- Once in the boot menu or BIOS (the BIOS may have a Boot menu option), you want to find the USB flash drive you created. It may be named something like ‘CBM FLASH’. You want to boot from the flash drive.
- You are booting from the flash drive if you see a blue screen with white text. It may take a while to load, but you should eventually see a screen like this:
- Press ENTER to start DBAN in interactive mode.
- On the next screen, use the
Kkeys to move to the cursor and press
SPACEto select the drive that you want to wipe. There will likely only be one option. The screen will look like this:
- You can leave all other options unchanged.
- Once you are ready, hit F10 to commence the wipe. You will see some progress indicators and a completed message once all finished. It will likely take 1-2 hours to finish.
- That’s it. The hard drive is now completely blank.
