Oh I see, ok then it makes sense. So to accomplish a dual boot setup, make sure the partition sizes are less than 128GB? Does the HDConfig tool automatically generate the 64MB partition? I deleted all partitions to start from scratch but those three partitions just keep coming back once I deleted them. So what I'm left with is a 120MB HFS, an 8GB SFS, and a 128GB SFS partition and 47.23GB left over as free space. No matter how I try and reconfigure the partition sizes, nothing ever sticks and it just keeps reverting back. What's worse is when I try to enter a value in MB, the whole system just locks up and I have to reboot.
