How can I install Linux Lite by the very beginning?

Hello DeepThought.

I don´t know what is a system with or without UEFI. But as I said before secure boot is disabled!

Just in case I am downloading that full UEFI version you mentioned. I hope your link is safe!  It will take a while until my download finish.

In Windows 10, click on Start, search for system information and under system summary look for bios mode. It should state whether your pc is running under legacy bios or uefi

Hello Moltke.

I tried with Rufos, but it does not work either. I continue with the same issue.

Oh well, that's too bad. It's never failed to me but I guess this can happen.

By the way, I see the file name and directory is a "UEFI test" !  Is this a test of the Linux O.S. ?

I am only interested on stable and secure versions of O.S.

It's a stable and secure release. I don't know why it's called like that but as far as I can tell is as stable and secure as the legacy one.
