Thanks, Jerry, for replying,
NO, my system info says I have Linux Lite 4.6 64 bit. I wonder why it's showing a different version on my info here on the forum. I downloaded the uefi 4.2 version, because the normal downloads wouldn't work on my chromebook, probably secure boot or something. Anyway, from there, I updated to 4.6. My chromebook is Acer Chromebook 15 CB5-571 Auron-Yuna.
