As you have seen, the bootloader (what gets installed when you use "Install OtherOS") is installed to the PS3's flash memory and not the hard drive. Anyway ... just type game at the kboot prompt to go back to the Game OS and format your drive there. If you play many PS3 games at all you'll want to use the 10GB to OtherOS option (using 10GB for Linux).
