A year ago I built my desktop to run Win 7 (not knowing building a mac was possible) and have been running the system no problem. I'll list all main components used on the bottom, but the jist of it is a SSD boot drive and a 2TB drive for all my files and application. I recently upgraded my SSD so I have two solid state drives and I wanted to have two separate boot drives with Mac OS 10.8 ML installed on the other. I didn't want to deal with any partitions because I wanted it to be as clean as possible with two fully operating operating systems, essentially two boot drives both of which could access the shared 2TB drive and the other boot drive if necessary. I even got MacDrive for the PC side and Paragon NTFS (installed on my laptop) for the Mac side, so being able to access the different drive formats has not been a problem.

Since I wasnt able to get Kakewalk past the boot1 error, i reverted back to the MyHack option updated the IOPCIFamily.kext to get past the hang at PCI Configuration
there is a way to fix this
1.boot using unibeast usb
i realise that people are frowning on tonys site but
the reason u r having this issue is these newer drives are "advanced Format" or 4k drives..
