@MagicLike@jeder there are 2 or 3 ext2+ drivers, but you cant install windows on them
and you more often then not they are "experimental", or read only.
if you want a data exchange (or shared) partition, ntfs in linux is way more mature then ext on windows. or use fat, though that one doesnt support posix attributes (unlike ntfs actually).
and if you are really adventurous, i think linux can actually boot from ntfs, unless they removed ntfs kernel support.
