Select disk X (choose the hdd that you wanna create the partition, and this hdd should have following criterias mentioned above)Ĭreate partition primary id=af size=XXXXX (size in megabytes, if you dont use size flag, it will use the entire free space, id=af is the flag for osx journaled partition type) Open command promt (CMD) and start typing Partition 4 = Primary or Secondary depending on your needs (if you made primary for 3, then definetely make secondary so you can create more partitions for windows which doesnt mind for storage.) Partition 3 = Primary for OSX (Back up purposes or you can just make secondary partition so you can create more space for windows storage Partition 2 = Primary for OSX (Can be Windows depending on your choice) Partition 1 = Primary for Windows (Can be OSX depending on your choice) What does it mean? How should I partition? To get the image on your head look at the order of partitions in my examples



There are couple of things you need to know before doing this.ġ You must have free disk space (non partitioned) on your hddĢ You should not have 4 primary partitions on your hdd where you have free space (because 4 primary means, no more partitioning)ģ In your partitioning scheme, you should not have secondary (extended) partition before the primary partition you will create for OSX (because if you do so, osx doesnt like to boot from it most of the time)
