I'm looking to explore multiple Linux distributions and have a few questions about getting started. First, how much space should I allocate on a USB flash drive to test out different distros? Is running multiple distros on one drive even feasible? Next, if I want to deepen my understanding of Linux, would it be better to start with Arch or Gentoo? Also, how much wear does installing various distros cause on HDDs or SSDs? Is there a specific method for safely wiping and reinstalling systems like Arch or Gentoo? What machine specs would you recommend for learning? Should I go for something slower or faster? Lastly, can I use an external drive to boot Linux if my only internal drive is occupied by Windows? What do I need to do to set this up?

1. Definitely possible with tools like Ventoy. If you want to run multiple distros, just plan on a 64GB drive to be safe
2. Gentoo can teach you a lot, but it’s quite complex. If you aim to learn quickly and practically, think about general-purpose distros first, then consider diving into Gentoo later.
3. Installing various distros won't necessarily 'wear out' your SSD or HDD quickly unless you’re constantly writing and erasing massive amounts of data. But it’s less of a concern with modern hardware.
4. For specs, you could use any computer—it's about what you're comfortable with. A slower machine will be fine for learning concepts but might be frustrating for heavier tasks.
5. You can absolutely use an external SSD to boot Linux. Just make sure to format it properly and follow the steps for dual booting if you decide to keep Windows as well.
That should be okay for very basic Linux tasks, but it might struggle with more complex operations. It depends on the distro; lighter ones like Puppy Linux could work well!
1. To handle multiple distros, you can use Ventoy to create a multi-ISO live USB. As for size, I’d recommend a USB drive with at least 64GB, especially if some distros can range from 300MB to 4GB.
2. When it comes to choosing a distro for learning, if you're new to Linux, I'd suggest starting with something like Linux Mint or Ubuntu for a smoother transition. Gentoo and Arch can be challenging if you're not familiar with terminal commands yet.
3. Newer SSDs and USB drives have better durability. For USB drives, they don't wear out as quickly these days. I’ve used a single USB for many different ISOs, and it still works fine! You can use the 'dd' command to overwrite old ISOs easily.
4. You can learn on almost any machine, even something low-spec. I’m currently using an old thrift store laptop, and it works great for learning!
5. Yes, you can boot Linux from an external drive. You might want to consider setting up a dual boot system if you prefer keeping Windows, but be cautious with boot settings to avoid conflicts. Guides online will help with this!
1. Using a USB with Ventoy is really effective for multiple distros. I’d say, aim for at least a 64GB drive for convenience.
2. It really depends on your current skills. If you're new, avoid Gentoo at first. Go for something user-friendly, and as you gain confidence, explore those challenging distros.
3. New USBs and SSDs are durable, but if you’re heavily experimenting, back everything up just in case.
4. Honestly, almost any old computer will work as a learning tool. I’ve used some pretty ancient tech for mine!
5. Booting from an external drive is completely doable. You will just need the right setup; dual booting is a solid way to keep using your Windows machine while exploring Linux as well.
I’m worried about messing up my Windows setup while doing a dual boot—any tips?
Definitely follow some reliable guides for dual booting and back up your data first! That way, you minimize risks!

I have some older machines that are about 200MB RAM and low HDD space. Would that work for learning?
