I'm trying to boot ubuntu 18.04.1 from my usb slot on my Dell XPS 15, which has Windows 10 as a normal boot. I getting the following error when I try this boot:
Invalid signature detected. Check Secure Boot Policy in Setup
This more than likely isn't an Ubuntu issue but could someone suggest a solution?
Never had this issue when I booted my XPS 13 with Ubuntu 14.04. Bios
