Dual Booting with Mint?

[LeopardBunny]

Hi, I'm trying to dual boot Kubuntu alongside Mint. Problem is I'm really new to Linux and it's been quite a learning curve for me so I need things explained like I'm five. I'm also not sure if my issue is a question for the Mint forums or for here, so I'm asking both.

There's a few things I want to be able to run that I need Wayland for, and to my understanding that's a part of the OS itself and something Mint doesn't currently support. A friend suggested to try Kubuntu. I tried making a bootable flash drive with Mint's built-in tool, and I thought I had installed Kubuntu fine, but it's not showing up in Grub. I noticed that the flash drive was not showing up as UEFI when selecting it for boot, which I didn't think much of at the time but suspect that's why the install isn't showing up. Is it possible to write the flash drive as UEFI with the Image Writer? Is there a better program I should use? Is this even the problem to begin with...? Please help, and please be patient with me because I'm far from knowledgeable about Linux.

but it's not showing up in Grub

You need to boot to Mint and update it's grub so that it sees the new OS.

sudo update-grub

You may also need to enable grub's OS-prober in order for this to work, though I think that Mint keeps it enabled, maybe, despite the potential issues brought up by the Grub devs, who decided to disable it outside of initial OS installs.

Note that each OS has its own boot loader, so the option to switch via the bootup hotkey is an option, or to switch boot orders in your BIOS. Kubuntu's grub should have seen Mint during the install and added it it to K's grub menu.

Hello LeopardBunny welcome to the Kubuntu forum, enjoy the journey!
Mint does support wayland but it's still experimental on Mint and I haven't had good sucess with it. When you install another Linux Distro the last distro you install will control grub so you need to go to that distro and run

sudo update-grub

command and it should find the other distro that you have installed. Good luck.

Actually, what do you need Wayland specifically for?

Since this is not a separate system but protocols implemented by each desktop compositor (kwin for Plasma) what feature you are needing might be available in xorg.

It's usually the other way around at the moment.

The only thing I can think of of the top of my head that needs Wayland but it's not available in some fashion on something using xorg is Waydroid.

Whe

Not true, in modern times,with EFI.
Each OS has it's own separate boot loader, so each Linux install has it's own Grub. Which one you see is what you set in your system firmware (BIOS). Luckily grub can boot multiple OS installs so you really do only need one.

Now, some motherboards will set the newly installed OS as the first in the boot order. My little HP does this but the board in my main PC does not.

Yeah, it's Waydroid. I'm planning to (hopefully) play some Plants VS Zombies 2 mods on it.

updating Grub worked! thank you!
