Trying to Install Elementary OS off a USB Drive

So I am Trying to Install Elementary OS off a USB Drive. And when I load from the USB drive, it says: Boot Failure A proper digital signature was not found. It may have said more I can't remember. Does anyone have any solutions. Thanks. I'm trying to install it on a Toshiba Satellite S855-S5378 laptop. Thanks!

Actually to update, I solved the problem. Just had to disable secure boot. Thanks!
