> Compared to that, I think formatting another partition to install ventoy to (in the use case you're outlining), or updating a grub config with code like `loopback loop (hd0,5)`.. for me, these take more effort and care. The other partition with the ISOs is not for when I plan to boot into a newer live ISO (which I would have to add to the partition etc): it's for when I don't plan to, or even want to!! The last time it helped me, I had made a configuration mistake on my laptop in an airport. "grab a spare thumbdrive, and install ventoy to that" would have been very painful, but rebooting and selecting from the UEFI grub2fm to then pick an ISO from which I could fix my mistakes was very easy (or at least, easier than the alternative!) However TBH I I hadn't had such a setup, I don't think I'd have taken the risk of doing some configuration and UKI tweaks at the airport while bored :)
