I have a new rMBP that was initially setup with 125 GB towards OSX and the remaing 375 GB towards bootcamp. Now I realize that what I really want are two smaller OS partitions and a shared data partition.
Is there an easy and free way to non-destructively shrink bootcamp to about 100 GB?
Is it also possible to format the remaining space so that both OS's can read/write to it (say using exFAT)?
Things I've tried:
GParted Live - for some reason I can't seem to create a bootable USB that the macbook will boot from.
Disk Manager in Windows - it won't shrink the partition past about 190 GB due to "unmoveable files." I've uninstallied stuff, disabled the page file, hibernation, system restore all to no avail.

The only program that is known to work for what you want to do is Paragon Camptune. There are no free alternatives aside from doing a format and reinstall.
If you want to have a shared data partition, you can use exFAT, but there is one thing to be aware of when doing this. Create the exFAT partition from within Windows, using a cluster size of 1024. While OS X can create such partitions, there is a high chance of freezes and data corruption unless you set it up inside Windows. Don't know why that's the case, but at least it's a viable workaround. -

Well I went ahead and reinstalled Windows. Unfortunately OSX decided to eat up the rest of the partion rather than leaving it free. When I go into disk utility to shrink it, it warns me that "changing the partition map may make this disk unbootable using Windows." Should I actually be concerned about this?
