Exact same problem. The only thing I can think of at this point is to rip out the hard drive, put it in an external drive, follow Oscar's suggestion using another Mac to initialize the drive using the Mac file system and retry. Will report back.

So I used a Linux USB key (Ubuntu 11.11 -- X wouldn't load by default -- ugh) and used parted to delete the default Dell diagnostic and XP partitions and tried again, but it won't see the drive at all. Now I can't even boot into XP :-)
I'm on BIOS A11. Any and all help is appreciated.
