Kali Linux (2021)

When turning on the computer, the computer sometimes makes a beeping sound (loud), and then shows a log of what the computer is doing, this all goes very fast, and is on a black background with white text.

These may scare people even more, but all of this is finished when a login prompt appears and you can type a command.
