From what I understand from both reading and discussion with others. If you try to do that big of an install from a Mac, oddly enough the iPod/iFlash/Rockbox will generally fail. However if you can get your hands on a Windows machine you should have no issues. I know, weird huh being the iPod and Mac's are BOTH Apple!!!!

No you shouldnt boot into Apple iOS on iPod 6 or 7 gen. In most cases youll loose everything and have to do it all over again.

From my experience if you run into trouble like that youll need to detete the MBR (master boot record) then delete all partitions. Next you create a new Fat32 Partition and finally you will Format the Partition also as Fat32 all I use is AOMIE Partition Assistant and its FREE. Then Apple iTunes will detect it soon as you start your ipod and plug in to computer, will be detected as an iPod in recovery mode. From there I think you know the rest from there. I hope that helped even if a little to late for supper. Lol
