<span style="color: #000000">Blancco Drive Eraser may face some issues when booting on machines that use EFI/UEFI. </span><span style="color: #000000">Blancco Drive Eraser</span><span style="color: #000000"> UEFI support (available from 5.4.x versions) requires some mandatory conditions:</span>

- <span style="color: #000000">Booting from a CD does not work properly, prefer instead booting with a bootable USB stick previously formatted with Blancco USB Creator. The USB Creator version has to be at least the 2.2.2 (or newer). Download the software from</span>[<span style="color: #000000"> this link</span>](https://go.docs.blancco.com/wiki/spaces/KB/pages/11633303)<span style="color: #000000">.</span>
- <span style="color: #000000">The UEFI machine where Blancco Drive Eraser is booted has to be an x86 based system.</span>

<u><span style="color: #000000">Disabling the Secure Boot (required on versions older than v6.3.0) *:</span></u>

<span style="color: #000000">Any PC with a Windows 8 logo sticker has a "Secure boot" enabled by default. Secure boot is an UEFI feature that makes Windows 8 very resistant to low-level malware such as rootkits. </span>  
<span style="color: #000000">Blancco Drive Eraser may not properly boot on a machine where the Secure Boot is enabled, in which case this feature has to be manually disabled. </span><span style="color: #000000">The following steps will demonstrate how to enable or disable the Secure Boot in the PC's UEFI settings:</span>

1. <span style="color: #000000">Boot to UEFI Firmware Settings.</span>
2. <span style="color: #000000">In the motherboard's UEFI firmware settings, go to the Security/Authentication (or similar) menu, select the Secure Boot option and disable it.</span>
3. <span style="color: #000000">Exit the menu and select Save Changes and Exit. This reboots the machine.</span>
4. <span style="color: #000000">Secure Boot can be enabled again, following the same logical steps.</span>

<span style="color: #000000">It is possible to boot Blancco Drive Eraser on a machine that has UEFI with a bootable USB-stick. Nevertheless, changing </span>[<span style="color: #003366">the booting options</span>](https://go.docs.blancco.com/wiki/spaces/KB/pages/11632792)<span style="color: #000000"> may not work on these machines as only the default booting option's parameters are taken into account. Try the following to overcome this issue: </span>

1. <span style="color: #000000">If the machine has UEFI and BIOS, the easiest solution is to use the BIOS-mode to boot the machine.</span>
2. <span style="color: #000000">If the machine has UEFI and no BIOS, you can create a bootable Blancco Drive Eraser USB-stick with the </span>[<span style="color: #003366">Blancco USB Creator (2.2.0 newer)</span>](https://go.docs.blancco.com/wiki/spaces/KB/pages/11633303)<span style="color: #000000">. This adds the Booting Options as a second menu right after the main boot menu.</span>

**<span style="color: #000000">*</span>**<span style="color: #000000"> Starting with Blancco Drive Eraser v6.3.0, the UEFI Secure Boot is fully supported. BDE will be able to boot on the machine whether the Secure Boot feature is enabled or not. Supports CD, USB and Preinstall booting. Requires Blancco USB Creator v3.2.0 (or higher) or Blancco Preinstall v2.4.0 (or higher).</span>
