Fedora 38 when I will be sure that I can have control on the full installation.
The risk is that I lost more control, typically on the installation of sda4

The way I test out new Fedora releases is to see if the live image works on my hardware.

The other way is that I have a external USB-3 SSD drive that I use for deeper testing that

needs specific software installed. For example when I had nvidia GPU I would test out the

rpmfusion drivers this way.

In both cases I do not need to figure out how to setup a single grub to work with OS installed

on 2 drives.

Having said that I wonder if you have two sets of BLS files that you need to merge into

your preferred /boot (assuming you have multiple /boot's and f38 and an f40).
