Re: [Trisquel-users] I am giving myself a non-proprietary challenge

I had to go through some scary things to get Trisquel set up on a friend's  
laptop, much like you do.
The BIOS settings threw some scary "Warning" messages, but when I disabled  
the option that's cryptically named, the USB worked.

"Clear Secure Boot Keys" is the option you want. It'll let you use the live  
USB, afterwards.
