Hi! So, i have a macbook pro. and i had win7 on bootcamp. And wanted to format win7 so i tried to erase the bootcamp partition in disk utility, i got error like "file system formatter failed" sth like this.. So i simply deleted that partition from my hard disk's partitions in disk utility. This is my hard disk situation now -> here And now i tried to create a new partition from that empty space. (I can create with all formats like in this pic) except the windows nt file system. when i choose to format with that i got the same error "file system formatter failed". But i tried lots of times with different formatting, whenever i open the bootcamp to install again the windows i take this screen. Can somebody help? Simply i wanted to uninstall and install win again, so i erased the bootcamp partition, now even if i partition with diff. formats i cant get the bootcamp work.
