Personally I would definitely focus on figuring out the underlying motivation for the OS hopping, but just in the interest of maybe saving some time having to re-setup everything you might consider:
- I’ve never used Windows 11 so it might have even more insidious tendencies than in the past, but generally the rule-of-thumb for multi-booting has always been to install Windows first. Other operating systems tend to be more considerate about not stepping on other installs they find and their boot loaders more flexible.
- If the budget allows you could also just use a different physical disk for each OS and either disable one in the BIOS or manually disconnect one to choose which OS to boot into.
- Maybe just running a virtual machine or live-boot would satisfy the FOMO aspect?
- Making a snapshot image of your configured install to restore from would also speed up the process of toggling between environments.
Just throwing out ideas, best of luck to you :)
