How do I uninstall endless os

english help
1

I bought a laptop online and it came with Endless OS. How do I get rid of it or install another OS? I researched this a bit. I tried accessing the BIOS or BOOT by pressing f-numbers, but the only thing, which redirects me to something is when I press esc, which gets me to GNU GRUB. What can I do?

Also endless doesn’t run .exe files, so I couldn’t install windows 10 from my bootable USB

You do indeed need to access the BIOS menu. Getting to GRUB is too late. What is the model of your laptop? On some computers you need to press Delete, or sometimes a special button next to the power button on the laptop.
