How to Install Windows 11 Without Secure Boot: A Step-by-Step Guide

If you’re looking to install Windows 11 but your system doesn’t support Secure Boot, don’t worry. Here’s a quick overview: you’ll need to create a bootable USB drive, modify it to bypass Secure Boot checks, and then proceed with the installation. It sounds technical, but I’ll guide you through every step.

Step-by-Step Guide to Install Windows 11 Without Secure Boot

In this guide, we’ll walk you through how to install Windows 11 on a system that doesn’t support Secure Boot. This includes creating a modified installation media and tweaking some settings to bypass the Secure Boot requirement.

Step 1: Download Windows 11 ISO

First, download the Windows 11 ISO from the official Microsoft website.
Ensure you’re downloading the correct version of Windows 11. Save the ISO file to a location you can easily access.

Step 2: Create a Bootable USB Drive

Next, use a tool like Rufus to create a bootable USB drive with the downloaded ISO.
Open Rufus, select your USB drive, choose the Windows 11 ISO, and click "Start." This process will erase all data on the USB drive, so make sure you’ve backed up any important files.

Step 3: Modify the Installation Media

Modify the installation media to bypass Secure Boot by adding a specific file to the USB drive.
Manually add an "ei.cfg" file to the "sources" folder on the USB drive. This file disables Secure Boot checks during installation. You can create this file using Notepad.

Step 4: Boot from the USB Drive

Restart your computer and boot from the USB drive to start the Windows 11 installation.
You may need to enter your BIOS or UEFI settings to change the boot order. Look for a message on startup that tells you which key to press (often F2, F12, or Del).

Step 5: Start Windows 11 Installation

Proceed with the Windows 11 installation as usual, following the on-screen instructions.
During the installation, the system may warn you about Secure Boot. Thanks to the "ei.cfg" file, you should be able to bypass these warnings and continue the installation.

Step 6: Complete Installation

Finish the installation process and customize your Windows 11 settings.
Once the installation completes, follow the prompts to set up your preferences, connect to Wi-Fi, and log in to your Microsoft account.

After completing these steps, your system will reboot into Windows 11 without requiring Secure Boot. You can now enjoy the new features and improvements that come with Windows 11.

Tips for Installing Windows 11 Without Secure Boot

  • Backup Important Data: Always back up any important files before starting the installation process.
  • Use a Reliable USB Drive: Ensure your USB drive is in good condition to avoid installation errors.
  • Check for BIOS Updates: Sometimes updating your BIOS can add compatibility with newer OS versions.
  • Disable Other Security Features: If you encounter issues, try disabling other security features like TPM in the BIOS.
  • Stay Updated: Keep an eye out for updates from Microsoft that might simplify this process in the future.
