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.

There shouldn't be any significant difference between the GRUB versions that come with different distros, so the order in which you install the distros doesn't really matter.
You can't install multiple distros on one partition, so you need at least one partition per distro.
Ok cool, thanks. Does the bootloader partition get created automatically by the installer or is that something you must do manually? and should each partition for each distro have it's own swap? or just one swap to handle all three?
The first installer will install the bootloader automatically.
It will also create a swap partition unless you tell it not to, and all distros will use all swap partitions by default, so you don't need more than one per disk.
If you don't hibernate one distro and then boot another, sharing a swap partition isn't a problem.
I appreciate the patience and helpfulness. Dont the distro installers automatically create a swap for you? if not, how large of a swap do you recommend and would that just be an empty fat32 or ext4 partition?
A swap partition doesn't have a filesystem - it has its own partition type and doesn't contain files. The installer might create one automatically or it might not - if it asks how large it should be, a good rule of thumb is to use the same size as your RAM.
If that turns out not to be enough, you can create a swap file on a data partition later and if it's too large, you just wasted a few GB but usually that doesn't matter.
Ok so then in this case, create one swap approximately the size of my RAM as I guess the first partition? and then each partition beyond would be just for the distros? i've scene diagrams of efi and bios partitions in the front too, what about those?
The order of the partitions shouldn't matter - usually the EFI partition comes first if there is one at all, but as far as I know that isn't actually required.
thanks, makes it sound easier then. but what about the mount points like I mentioned? and do people make their own partition for the home directory??? and how does a storage partition integrate with three different distros? I just want to make sure I cover all my bases.
You can create dedicated partitions for /home, but unless you know why it makes sense in your specific situation, you shouldn't.
The data partition is just another partition that you can mount somewhere, for example /mnt/storage.
Gotcha, thanks again. Now creating these partitions is a bit more clear, now I have to learn about mounting and all of that. No clue on that side of things
