I have an Acer predator laptop that dual boots windows 11 and Xubuntu.
What computer are you using that's so locked down?

It's an ASUS Vivo book X515JA. Every time I try to install Linux from a bootable USB it just ignores the boot order and goes straight to loading Windows.
I have been successful in installing a secondary Linux system alongside Windows, but everytime Windows has an upgrade I lose my Linux system. I just want to get rid of Windows entirely. I should probably have another crack at it I suppose.
