Internal disk has 3 volumes but I want to remove the Macintosh HD

Hello! I am so confused after researching a few related discussions about this. This is what I am trying to do:

Can I remove/erase Macintosh HD to get my storage back?
How can I do it?
How to create a partition for two different macOS? What is the best way?

This is my Disk:

The current one I am using is Macos, not the Macintosh HD. Because, I had an issue of booting into it before that's why I urgently created another, which is Macos. Bootcamp needs to still be there as well.

I appreciate all the help. I have been trying to find a solution for quite some time now.

MacBook Pro 16″, macOS 14.6

To be sure, can you give us a screen shot of " The current one I am using is Macos "

We what to be absolutely certain "MacOS " has the mount port of /System/Macos

If it Does have that Mount point >> /System/Macos

Yes you can remove " Macintosh HD " using the Minus Sign in Disk Utilities

As for installing another version of macOS on the same computer

It Not Suggested to Partition an APFS / GUID formatted drive which it would be as it is running macOS 14 Sonoma

It Is suggested to this method outlined by Apple

I read somewhere that it is the main macos, something something, and removing it would not allow you to boot up your macos without using a USB?

I really don’t know anything about any “something, something.”

On Apple Silicon, the secure boot information is stored on the internal drive, not specifically in the System Volume.

Here are the instructions (note the lack of cautions): Use more than one version of macOS on Mac - Apple Support

You do have a backup of the other system, right?

Yes but I had no important data on there. So If I remove it would I get the used up storage back into Macos?

Will I have trouble booting into the system? I read somewhere that it is the main macos, something something, and removing it would not allow you to boot up your macos without using a USB?
