If I remember correctly, the older Macbook pro models (pre 2011) had a 4 partition limit: so, if you tried to install multiple operating systems, you had this limit.

Do the new models (2011) still have this limitation? I'm planning to install two Linuxes, A Windows and a Mac partitions to boot.

This is not a limitation of the hardware. This is a limitation of the MBR partitioning scheme required to allow Windows to boot with other non-Windows operating systems. The MBR partitioning scheme only supports 4 primary partitions.

The GUID partitioning scheme that Mac OS X uses by default is able to handle more that 4 partitions but not all operating systems support GPT.

So, I'm stuck on 4 partitions only if using windows... right? – Somebody still uses you MS-DOS Aug 11 '11 at 17:27
If Windows 7 can boot from a GPT partition formatted as FAT32 or NTFS on a Mac (not something I've tried) then no. You can create as many GPT partitions as you like. – Asinine Monkey Aug 11 '11 at 17:41
Well, it seems from the link you posted that Windows 7 64 bit can Boot from GPT on EFI, I need to read all these links completely to see the caveats of these approaches. – Somebody still uses you MS-DOS Aug 11 '11 at 17:50
An interesting link about GPT and ubuntu on a mac: – Somebody still uses you MS-DOS Oct 25 '11 at 4:42
