Why is my Linux computer not booting at all?
Linux does not usually give as many problems when starting as Windows, since, badly, even if we do not reach the desktop, at least we can load a basic TTY from which to repair the system. However, it can fail. And the most common failures that can cause this system to not boot are either boot loader (GRUB) or hard drive failures.
