I just deleted the System Folder, it installed the final

I didnt apply nforce 1.1 ppf or whatever it is. (the one after 5)
I do not have the looking for root device issue.
So I don't think I need the fix unless it fixes the following:

any DVD will not mount and trying to look at System profiler then Serial ATA or starting Disk Utility to see if it will mount the dvd that way, or even trying to eject the disk via iTunes, or eject icon on menu bar, causes System Profiler, Disk Utilities, iTunes, etc in Force Quit Dialog Box to show up as non responsive, this occurs with any non blank DVD in the drive.

Update: It thinks these DVD's are blank.
