Hello,
today I tried to install Ubuntu on my MacBook but when I start from the USB-stick, an error appears and it says that "Continuing boot because secure boot is disabled.
What should i do?
I have already tried to do it at Disk Utilities on Startup Secure Utility but on this menu, I can just add an firmware password nothing else.
Im currently using MacOs Catalina 10.15 on my MacBook.
Tried every possible solution.

Best regards
Ibtasam
