The only thing that could cause you problems is Secure Boot but you can disable that from the UEFI settings menu. Hit the bios key during bootup and it should take you there.

Look for the option when installing that is along the lines of "wipe entire drive."

If you want Debian, check out Vanilla OS. They reached a milestone not too long ago, and it's a bulletproof distro. It containerizes most programs, it's immutable, and has atomic updates.

Someone already mentioned, turn off secure boot in your BIOS/uefi settings.

If you are using a typical distro like fedora, debian or ubuntu, and you are wiping everything, you don't really need to know anything. The installer will handle everything for you. Just delete all partitions while installing and start fresh and it should all just work.

If your install media refuses to boot for whatever reason, then you may have to disable secure boot in the system EFI/BIOS menu.

Won't make much of a difference usually. Worst that may come up is having to import the key from the distro during boot of your flashdrive. Otherwise go through the installer, delete windows or tell installer to wipe the disk and install over windows.
