Hello all. If this is in the wrong section, I apologize to the Mod - feel free to move it.

Basically, I have every OS installed, but not even Refit will load my other partitions. I can boot into OS X 10.6, but neither Windows nor Linux show up.

I'm on Macbook Gen 6, if that matters, and here is my disk information:

Code:
diskutil list /dev/disk0 /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *250.1 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS SAUCIN 169.6 GB disk0s2 3: Microsoft Basic Data WINDOWS 55.0 GB disk0s3 4: Microsoft Basic Data LIN 20.0 GB disk0s4 5: Microsoft Basic Data SWAP 5.1 GB disk0s5
Code:
sudo fdisk /dev/rdisk0 Disk: /dev/rdisk0 geometry: 30401/255/63 [488397168 sectors] Signature: 0xAA55 Starting Ending #: id cyl hd sec - cyl hd sec [ start - size] ------------------------------------------------------------------------ 1: EE 1023 254 63 - 1023 254 63 [ 1 - 409639] <Unknown ID> 2: AF 1023 254 63 - 1023 254 63 [ 409640 - 331213200] HFS+ 3: 0B 1023 254 63 - 1023 254 63 [ 331886592 - 107419648] Win95 FAT-32 4: 0B 1023 254 63 - 1023 254 63 [ 439308288 - 39059456] Win95 FAT-32
Anyone know what I need to do to make my partitions boot? I've run out of ideas.

Any help would be more than greatly appreciated!

Someone from another forum suggested I rewrite the MBR using Terminal after booting from my OS X DVD,
Code:
fdisk -u /dev/rdisk0
but that didn't work. Anyone have other ideas?

Well, the only suggestion I have is Googling about how to triple boot a Mac. One of the first results was a boot manager that allows you to select between OS X, Windows, and Linux.

OSX requires a GUID partition table. Windows requires MBR and cannot boot from USB. Linux has noneof the aforementioned limitations.

Therefore, you need two hard drives. Can you live without a CDROM drive?
