This topic may have been covered if so please accept my apologies. This article may be useful to windows users looking to boot into Linux Light. The secure boot disable option is of course up to the producer of the computer. Mine had windows 10 and fortunately I could disable secure boot and engage legacy to boot Linux Light or any other Linux distro that may not have a key for Microsoft. Hope it helps.
