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.

You can boot Linux from a USB flash drive if your main installation isn't working. That might be better than searching for solutions from your phone. And a bootable USB flash drive is helpful when you can't boot from the internal drive. I always have one around, just in case, though I don't use it very often.
Booting from USB flash drive is a bit slow. A USB attached hard drive or SSD will be much faster or, if your internal drive is big enough, you can partition it to hold two Linux installations. Then, when one isn't working you can switch to the other with just a reboot, as long as it's not the boot loader that's broken.
