From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

No EFI environment detected?
Sounds like someone deleted the EFI partition maybe.
Or the machine is so old it still has a BIOS.
Doesn't every computer have a bios? Genuinely asking
I think (not 100% sure) that UEFI is a replacement for BIOS. All modern computers use UEFI.
People still colloquially call it "BIOS" because it serves a similar purpose, but there is a technical difference.
You are in fact correct. UEFI (Unified Extensible Firmware Interface) is the modernized version of the very very old BIOS (Basic Input/Output System).
It brought a parade of improvements including the GPT (GUID [Global Unique Identifier] Parition Table) partition table replacing the old MBR (Master Boot Record) partition table.
