NTFS works on all platforms: with VFAT, it's the lowest common denominator between Windows, Linux, Mac (even if was read-only on mac the last time I checked) and far more resistant to damage than ExFAT. Like you, I also hate grub and prefer UKIs, but grub2filemanager is just a list to pick ISOs like in Ventoy, so I'm fine with it! To do the job, grub only needs to show me the list of files and read the ISO file when I select it. There's no need for a write access, so no need for ext4 - also, if I was using ext4, I couldn't see the files or add new ones from Windows I can use the same partition as the Windows recovery partition (where .wim files are stored) - this is a dirtier trick, but a Windows recovery partition is needed to boot Windows with Bitlocker, so why not put it to a good use and keep other files? It's a "special" partition so I can be sure Windows won't touch them and won't easily let the partition be mounted (or formatted by accident) Overall, it's easier for me to keep this same standard partition scheme everywhere (efi=part1, msr=part2, ntfs=part3, regular OS=part4+) as it's peanuts (even with a 1G EFI and a 10G NTFS) in comparison to the comfort it provides
