The Dutch OS/2 VOICE foundation is pleased to announce the release of a tool to install the ArcaOS Secure Boot certificate on your system. In the ZIP file you will find a PDF which explains how the tool can be used and when it's needed. The sources are also included, the tool is published under the GPL 2 license. This tool can only be used a computer running ArcaOS 5.1.0. or higher and ArcaOS should be installed in UEFI mode. This tool does not work with OS/2 or eComStation as these OS'es do not support UEFI. If you have any issues please send an email to helpdesk at os2voice.org.This tool might not work on all computers, especially older laptops. Some computers might not have a so called user mode in the UEFI setup (please check PDF file in the ZIP file for details).

Enabling Secure boot on your PC might be required if you have Windows 11 installed next to ArcaOS. You can read some details here: Can You Disable TPM and Secure Boot After Installing Windows 11? What Happens…

There are indications that Windows 12 will have Bitlocker (disc encryption) enabled by default,  then secure boot must always been enabled.

When you unzip the file make certain the files end up in the subdirectories under directory SBOOT. On ArcaOS you can use the Archive Tool  to unzip the ZIP file.

You can download the tool here: Secure Boot tool for ArcaOS (version 1.0).
