The “Selected boot Image did not Authenticate” error occurs whenever you are trying to boot your PC from an external drive when Secure Boot is enabled. It also occurs when you attempt to boot to an Operating System (OS) that does not support this option, regardless if it’s on a single-boot or a multi-boot system.
The reason for such an issue is that this boot mode uses security keys to ensure that the bootloader is loading only trusted OS into your system. So, whenever youboot using a USB driveor to an incompatible OS, Secure Boot restricts the authentication.
In some cases installing another OS to your PC or updating the UEFI enables the Secure Boot option. So you may encounter this issue in such a scenario even if you had previously disabled the option.
