When I did updates in Zorin and restarted my laptop, I got the following message " setup Notice, Ubuntu has been blocked by the current security policy."
Anybody have a fix for this? Thanks
This sounds like a boot problem. So are you able to get into the OS itself, or are you stuck at this screen? (Screenshot would never hurt 
).
Do You have Secure Boot in BIOS active? If yes, disable it and try it again.
I have my laptop set up with a dual boot system. I was able to boot to Windows 10 or Zorin. When the message comes up, if I click ok, it boots Windows. I can't get to Zorin.
I don't know. How do I disable it?
It's a BIOS setting, but every BIOS is different so there's no single set of steps I can outline for you, unfortunately.
This guide will help you find and disable it:
Also, if there is any mention of sbat in the boot errors, check this guide:
You must go into Your BIOS. There look for a Function called ''Secure Boot'' and check if it is disabled. If it is enabled, disable it. Then try if it works.
It could be that it is a Problem caused from a Microsoft Windows Update (You wrote that it is a dual-Boot System). Until it is ready the easiest Thing is to disable Secure Boot in the BIOS.
Okay, I followed the instructions and that worked. Thanks for your help.
