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.

I'm running a very old dell optiplex 710, it has uefi but no option to turn off secure boot.
The messages you're getting sound like they're from the bootloader, so I think secure boot is not causing the problem... Linux should print some stuff right away when it loads, maybe check the architecture of the kernel you're trying to boot, even an error immediately after loading the kernel should print something unless the architecture is so different that it's just feeding the CPU bad instructions... Not sure how the bootloader would get installed correctly in that situation though. Is this after installation? Does the system boot from a live USB or cdrom?
