After doing the boot camp for window 7, when I restart my computer to install the windows 7, there's this part where you need to select the hard drive for the windows. When I try to select, none works even the one I partitioned for windows 7. Any idea?

Do you mean format while I'm downloading the windows 7 from bootcamp or while installing the windows 7 after I downloaded and restarted

I'm at the windows installer now.

I'm stuck at the: where do you want to install windows?

They give options of disk 0 partition 1, disk 0 partition 2, disk 0 partition 3 and disk0 partition 4 . Partition 4 is the one made when I opened the boot camp and downloaded the winds 7. But none of the partitions work. They all cannot be selected to continue the installation. When I press show details it says windows is unable to install to the selected location. Error 0x80300001. What can I do then?

These no boot camp in the options ); I'm totally lost now

But..I pressed advanced options and clicked format for that partition. And then instead of the message saying that I need to format int to ntfs or nfts or something like that, it changed to just say windows is unable to install in the selected location. Error 0x803xxxxx so I'm guessing it's formatted but there's another problem
