Beginner's Guides for Switching to Linux?
(lemmy.ml)
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.

Grub is a bootloader. Instead of starting Windows immediately when you turn on the computer there is a program called grub that is started. In grub you get a menu where you can choose what OS, Windows or Linux, you want to start.
Now, Microsoft doesn't like that because in their world there is only one OS so why would you even need to choose? 😉 So what Windows does sometimes is to remove Grub and make sure the computer starts directly into windows.
If this happens you just Google and you will find how to boot up on your Linux DVD/USBstick and run some commands to get the menu (Grub) back.
Ah okay that makes sense. I wasn't familiar with the term, but I've heard of bootloaders.
