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.

The only thing you would have achieved that was would be to copy an iso file onto your stick. EFI or Boot doesn't know how to do anything with it.
A lot of Linux ISOs are hybrid images which can be booted if flashed directly to a USB stick.
Op was just using
cpto copy the iso onto the drive no flashing or anything...The cp command will write the ISO file directly onto the device. This is the official way that is recommended by Debian:
cp debian.iso /dev/sdX
Source: https://www.debian.org/releases/stable/amd64/ch04s03.en.html
Woah...
Damn I'm sorry for questioning this method, I didn't know.
This works because block devices like
/dev/sdXare just files. If youcpa file onto another file, it overwrites the data of the destination with the source. A block device represents the device itself, not the filesystem; if you wanted to put the ISO inside the filesystem, you'd have to mount it first.Next time I'll test out another distro I'll try just that... Sadly I just hopped yesterday from Fedora 40 to LMDE.
