What tools can I use to resize and create a secondary HFSJ partition to install a secondary copy of Lion on? From what I can tell, Apple's GUI Disk Utility wants to reformat my entire drive to simply create a secondary partition. I've been looking at the terminal commands a bit, and I'm guessing there are some commands I can use to make this happen.
To provide a bit of history, I have been running Hackintosh as of when I got my Sabertooth x58 board with an i7-950 processor a couple years ago. From what I read at the time, my hardware seemed quite compatible. I dove right in and I had successfully installed and booted Lion 10.7.2. Upgrading to 10.7.3 was not a big deal. But 10.7.4 caused me a little more troubles. So far, I had been fine using my Lion 10.7.2 installer USB stick as a form of recovery, but 10.7.4 ended up requiring me to downgrade a kext to get it booting again. I ended up using my Windows 7 install with Macdrive to aid in copying over kexts, but I have realized it would be a lot easier if I had a secondary Lion install to fall back to.
I apologize if this belongs in another section, but I figured this one would fit the best as I do have a working installation.
