Understanding Secure Boot
Secure Boot is a feature of the Unified Extensible Firmware Interface (UEFI) that helps to prevent unauthorized firmware, operating systems, or bootloaders from running on your computer. It does this by verifying the digital signatures of these components before they are loaded. This helps to ensure that your system is running only trusted software.
The Error Message
The error message in question indicates that the system is unable to find the necessary files to boot from the USB drive in a Secure Boot environment. Specifically, it is unable to find the \efi\boot\mmx64.efi file, which is required for the system to start the MokManager.
Resolving the Error
To resolve this error, you will need to create a new USB live environment with the necessary system files. Here are the steps to do this:
Download a trusted ISO image of your operating system. Make sure that this ISO image is compatible with Secure Boot.
Create a bootable USB drive using a tool such as Rufus or UNetbootin. Make sure to select the option to create a bootable USB drive with UEFI support.
Boot your computer from the USB drive. If Secure Boot is enabled, you may need to enter the UEFI settings and disable Secure Boot temporarily. Once you have successfully booted from the USB drive, you can re-enable Secure Boot.
Once you have booted from the USB drive, you should be able to see the option to install the operating system. Follow the on-screen instructions to install the operating system.
