Your disk could not be partitioned. Win7 Bootcamp

I'm attempting to load Win7 on MBPr with Bootcamp 5.0 and am getting the error "Your disk could not be partitioned. An error occurred while partitioning disk." No other information leads me to understand the problem. Does anyone know anything about this error and how to fix? User uploaded file

MacBook Pro, OS X Mountain Lion (10.8.3), 15-Inch, 2.53Ghz, Mid 2009.

yes Dear Loner T,

Here is what i did at last, after editing info.plist of BCA, i was unable to create a partition via BCA, BUT i was able to initiate windows installation process in the EFI startup mode. then i decided to create a partition manually with ** and install windows on it so i created it but there was another error in windows installation partition choosing page.

Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks.

I tried to change the partition table but it wasn't successful so i deleted all of the partitions (even mac partitions) with windows partitioning tool and now my computer is running windows but there is no Mac OS. 🙂🙂🙂

When i was creating the windows partition i left 200 Gb of free space for future. Now i am trying to install Mavericks along with the windows installation but when i starting my mac with mavericks dvd and trying to create a partition with ** it stuck on preparing disk for partitioning and nothing happens for hours. 😟. this mac is really driving me crazy.

1. Using EFI boot to install Windows on a preUEFI Mac will cause issues because the Apple BC drivers will not see hardware properly or some will be missing.

2. Once EFI boot is installed using Windows diskpart, you have to manipulate the partitions to allow an EFI partition which will allow Yosemite to put the Apple Firmware in it for booting purposes.

3. Please be aware that you will run into many issues.
