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.

Tips on running multiple distros together on my laptop? (lemmy.ml)

Hello all, sorry for such a newbish question, as I should probably know how to properly partition a hard drive, but I really don't know where to start. So what I'm looking to do is install a Debian distro, RHEL, and Arch. Want to go with Mint LMDE, Manjaro, and Fedora. I do not need very much storage, so I don't think space is an issue. I have like a 500+ something GB ssd and the few things that I do need to store are in a cloud. I pretty much use my laptop for browsing, researching, maybe streaming videos, and hopefully more programming and tinkering as I learn more; that's about all... no gaming or no data hoarding.

Do I basically just start off installing one distro on the full hard drive and then when I go to install the others, just choose the "run alongside" option? or would I have to manually partition things out? Any thing to worry about with conflicts between different types of distros, etc.? hoping you kind folks can offer me some simple advice on how to go about this without messing up my system. It SEEMS simple enough and it might be so, but I just don't personally know how to go about it lol. Thanks alot!!

For the bootloader questions: You just have to go to your bios (spam a function key during start up, which function key depends on manufacturer) and change the boot order. The order of things which happen when you startup your machine is:

your bios starts up
your bios selects the highest priority bootloader you have (you want this to be grub)
you can choose which OS to open in grub, if you don't choose, it goes with whatever is set to be default in the grub config. If you haven't edited the grub config, I think this would either be the first installed OS or the first alphabetically
grub runs the startup sequence for the chosen OS

For the other questions: You might have to manually choose what to mount where. For each distro, you will want to mount a boot partition (your grub partition), a swap if your ram is low (make all your distros share the same swap partition), and a unique home partition.

You might also want to mount a shared files partition. These would be files you want stored locally that you can access from all the distros. Don't mount this in the install process, instead mount it after you install from whatever file manager you use on each distro. Make a ~/shared folder and mount it to that.

now this version sounds more simple. SO create three ext4 partitions roughly 50-60gb for each distro, maybe create a swap or maybe a storage partition? I don't understand how the storage partition would come into play, but I can just save anything important to my cloud drive anyway, so I don't necessarily need extra on device storage. So is that really it?

As for how exactly you add each distro to the grub config, refer to the distro specific grub instructions. Some user friendly distros auto detect and add themselves to grub, but some of the more customizable and bare bones distros need manual config.

awwee damn, thats another aspect I wasnt aware of. Are you referring to fstab or the actual grub config?
