Why use a 3rd party to create a multi-boot macOS? You can simply open Disk Utility and create a new APFS volume inside the APFS Container and both volumes will share the free space. It is non-destructive, requires no volume resizing and can be safely deleted as needed. You merely need enough free storage space. It enables one to multi-boot different installations of macOS. Holding power during startup on Apple Silicon to toggle between boot volumes.
This is how I test new macOS versions, I install using an APFS volume so it doesn't replace my working system. Once I am confident an upgrade will work properly. I decide to either upgrade in-place the existing macOS or I migrate my data from the original volume and then erase the original volume.
You just need to name the volumes so you can tell them apart. i.e. Sequoia or macOS15 instead of 'Maciintosh HD'.

I think Dg6.2.3 is NOT READY FOR AN MAC running an Apple M3 chip They never had this sort of issue with intel chip Macs. Unfortunately they do now and further never reply to tel calls or emails seeking assistance.
Booting a Mac from an external disk is still possible with Apple Silicon but it still requires the internal SSD to be working and bootable. If you break things badly enough you will require a second Mac and a Thunderbolt data cable so you can bootstrap the bricked Mac and reload macOS via the second working Mac running Apple Configurator.

Hi James,
thanks for your advice. However, that not the problem. I can boot with a USB drive to boot from after installing a “minimal” Mac OS 15.0.1. But that’s not the issue. When o try to create a the 32GB boot well drive
in DG6.2.3, the installer deletes every on the drive before doing anything else & it no longer works.
Does anyone have success in using the new Drive Genius 6.2.3 on a 2024 M3 running OS15.0.1and trying to create a bootwell drive? It doesn't work for me.
