    I'll throw all the details here so this might be long:

    I'm running a MacbookPro4.1 (Early 2008 model).
    Processor: 2.5 GHz Intel Core 2 Duo
    Memory: 4GB 667 MHz DDR2 SDRAM
    Graphics: NVIDIA GeForce 8600M GT 512MB
    Software: OS X 10.8.2 (12C60)
    Boot ROM Version: MBP41.00C1.B03

    I fresh installed Mountain Lion. Then set up three addition partitions. I installed Windows 7, and updated it. WIndows 7 still worked at that point. Then, I installed Linux Mint. I followed the instructions on this thread that has more details:

    Toward the end of the guide, I installed Gdisk and ran:
    sudo gdisk /dev/disk0
    GPT fdisk (gdisk) version 0.8.5
    Partition table scan:
      MBR: hybrid
      BSD: not present
      APM: not present
      GPT: present
    Found valid GPT with hybrid MBR; using GPT.
    Command (? for help): r
    Recovery/transformation command (? for help): p
    Disk /dev/disk0: 488397168 sectors, 232.9 GiB
    Logical sector size: 512 bytes
    Disk identifier (GUID): 7309B92F-DD71-449D-9D9B-F2E29E86E591
    Partition table holds up to 128 entries
    First usable sector is 34, last usable sector is 488397134
    Partitions will be aligned on 1-sector boundaries
    Total free space is 1272637 sectors (621.4 MiB)
    Number  Start (sector)    End (sector)  Size       Code  Name

    Recovery/transformation command (? for help): h
    WARNING! Hybrid MBRs are flaky and dangerous! If you decide not to use one,
    just hit the Enter key at the below prompt and your MBR partition table will

    Do you want to proceed? (Y/N): y
    OK; writing new GUID partition table (GPT) to /dev/disk0.
    Warning: The kernel may continue to use old or deleted partitions.
    You should reboot or remove the drive.
    The operation has completed successfully.
    (to clear up the confusion, although partition 3 says to be Linux, it is windows and partition 5 is linux)
    After writing it, it didn't change the table. I re-booted on a live Linux Mint OS, ran gdisk and it gave me the same table with partition number 5 as 0700. I rewrote it, and partition 5 still remains as 0700. However, although 0700 is correct for partition number 3, so shouldn't it still boot windows?

    Then I opened the fdisk and here is what I got:
    sudo fdisk /dev/disk0
    Disk: /dev/disk0	geometry: 30401/255/63 [488397168 sectors]
    Signature: 0xAA55
             Starting       Ending
     #: id  cyl  hd sec -  cyl  hd sec [     start -       size]

     2: AF   25 127  15 - 1023 254  63 [    409640 -  330467952] HFS+        
     3: 07 1023 254  63 - 1023 254  63 [ 332148736 -   58853376] HPFS/QNX/AUX
     4: 83 1023 254  63 - 1023 254  63 [ 430064613 -   58332032] Linux files*
    If you have any other ideas throw them out there and I will be happy to hear; however, I am generally looking for one of two conclusions:

    a) How to fix the tables to boot Windows and Linux or
    b) How to remove the partitions and fix the tables so that I can restart and dual-boot Linux and Mac OS X

    this should help your problem

    1st step
    * Set up disk with 2 partition's
    * install OS X to partition 1
    * Use "Empty Space" for partition 2 for Mint & Windows 7

    * Setup Partitions for Mint & Windows 7
    * Boot Mint and Create 2 Partitions formatted as FAT32 on "Empty Space" with gpart.
    * Leave 128 MB empty space in front of each Partition.
    * Label Partition table so it looks like this:
    Disk 1 = EFI
    Disk 2 = OSX
    Disk 3 = HDRecovery
    Disk 4 = Mint
    Disk 5 = Windows 7​

    * Install Windows 7 to Disk 5
    * "Format" Disk 5 from Windows Install Menu, "DO NOT DELETE"
    * If you get error message "can not install to gpt". Use gptfdisk and fix MBR. Needs to be Hybrid GPT.

    * Install Mint to Partition 4, format partition as ext4
    * Set bootloader to install to /dev/sda
    * Use grub2 for boot loader, it should be default loader. I've never used Mint, so I'm not 100%. Do not set boot loader to use "grub.efi" after you get install. You will be booting from Hybrid GPT.

    FYI -
    * You cannot triple boot using ACHI / EFI with Windows 7. Windows 7 only going to work on Hybrid GPT. It's pain in a** to boot Windows7 on GPT as dual boot. There has been some success, you will need to check out this thread on Mac Rumors for more info.
    * You can dual Boot OSX & Linux with ACHI / EFI
    * If you Upgrade to Windows 8, triple boot will work on GPT Partition Scheme using EFI for all 3 OS's.
