<span style="color: #000000">Sometimes Blancco Drive Eraser / Blancco 5 might not boot up properly from a USB or CD. Error messages, such as</span>**<span style="color: #000000"> "Cannot find application image"</span>**<span style="color: #000000"> or </span>**<span style="color: #000000">"Blancco image damaged, MD5 Checksums don’t match"</span>**<span style="color: #000000">, might be displayed on the screen.</span>

<span style="color: #000000">The most common CD boot related problems:</span>

- <span style="color: #000000">The CD/DVD is burned incorrectly.</span>
- <span style="color: #000000">There is something wrong with the CD or the optical disc drive: Read errors may result in error messages. Try re-burning the disc and make sure that the optical drive is functional.</span>
- <span style="color: #000000">The erasure software ISO image has corrupted (usually during the download): Re-download the ISO image and try the CD burning again.</span>
- <span style="color: #000000">Older optical drives can be picky when it comes CD-R/RW brands. If all else seems to fail, try a different CD brand, and burn the CD with slower burn rate.</span>

<span style="color: #000000">The most common USB boot related problems:</span>

- <span style="color: #000000">Something has gone wrong with the bootable USB device creation: See</span>[<span style="color: #000000"> this article</span>](https://go.docs.blancco.com/wiki/spaces/KB/pages/11633303)<span style="color: #000000"> for proper</span><span style="color: #000000"> bootable USB creation.</span>
- <span style="color: #000000">USB booting is not properly supported by the computer: This happens mostly with older computers, which might not support USB booting at all or it is badly implemented. Check if BIOS is able to detect the connected USB device or if there is even an option to boot from USB available.</span>
- <span style="color: #000000">Old version of Blancco USB Creator has been used:</span><span style="color: #ff0000"> </span><span style="color: #003366">[Download and install the latest version of Blancco USB Creator](https://go.docs.blancco.com/wiki/spaces/KB/pages/11633303)</span><span style="color: #003366">[.](https://go.docs.blancco.com/wiki/spaces/KB/pages/11633303)</span>
