Fedora; from its 'flagship' Workstation, to their glorious Spins and their Immutable Desktops

Fedora Silverblue - pretty well-known at this point, but it’s championing immutability

Couldn't have said it better!

An example of an installable immutable OS is Fedora Silverblue. Notably, you can change the "distro" flavor of Silverblue to try out KDE and then just flip back to Gnome. Each change is seen as an "update" that just moves you over to the new GUI. The article below explains a bit more.

I guess something like Fedora Silverblue might offer you something (to paraphrase) "stupid proof". For example, in this case the rpm-ostree rollback command would have been sufficient. Disclaimer: rpm-ostree builds images, therefore it's by necessity slower than apt. Futhermore, until this change is merged and deployed you'd have to reboot for the changes to apply. You might want to look into Distrobox as well, perhaps it can solve your problems without having to change your distro.

However, I'll add one more that I'm especially fond of. It's one of the most 'stable'\1]) Linux desktop systems\2]) without sacrificing access to the latest kernel-updates and packages. It comes bundled with everything\3]) necessary for productivity right out of the box and is built on top of the fundamentals laid by Fedora's Immutable Desktops. Allow me to introduce uBlue; I know that I'll undersell it regardless, so I recommend you to check the provided link instead.

OS: Fedora Silverblue

Ventoy is an open-source tool to create a bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. Using Ventoy, we can create live USB for multiple distros in one flash disk. This is a revolutionary feature compared to other tools, e.g., Etcher, Rufus, etc, that can only create one live USB at a time. This tool is so important. Don't call yourself a distro hopper if you don't know this tool.

I'm thinking you mean Ventoy? They say they can load vhd and img files, though I've only tried ISO's myself.

I faced it too. There is a PR on the ventoy GitHub repository that fixes Proxmox boot.

I find ventoy more tedious, because you can't use it on your hard drive with a sane partitioning scheme.

The only reason is because of how the ventoy detection hardcode the partition boundaries in its checks, and it means Ventoy can only run with the partitions set in a way that may lead to alignment issues like write-amplification: I've detailed that in https://github.com/ventoy/Ventoy/issues/1342

Ideally I'd have a 10G partition after the EFI (or it could even be the EFI itself) with a few ISOs for rescue purposes + a UEFI entry to avoid having to use a bootable USB, but that's not possible with Ventoy unless I accept Ventoy choices of partition boundaries:

I downloaded and made a bootable USB Ventoy (https://www.ventoy.net) with its Windows GUI app in my updated 64-bit W10 Pro PC. However, I couldn't seem to get VirtualBox v7.0.12 to boot it. I read VirtualBox can boot from bootable USB flash sticks so it should work. Am I missing something?

So, yes. The installer will need to install grub to that first partition. You can install ventoy to a usb drive, put a windows iso there and your q4os iso. In case you mess up big time, you can reinstall windows.
