“A possible solution it’s to split your hard drive in multiple
partitions and dedicate each one to an Operating system, so for
example you could have 25% of your disk with a Fat32, 25% with NTFS
and 50% with Ext4. Personally i don’t like too much this solution,
sure you can use a native file system in every operating system,
but you also have all the possible problems in mounting a different
FS, and I’m sure that I happen to have the right documents in the
wrong partition.“So, for me the best solution it’s to have 1 partition and 1 big
filesystem.”
