Alright I've partitioned my drive into 3 using disk util sda1 default mac boot or whatever, sda2 main OSX, sda3 arch, sda4 win7.
I've installed win 7 already, and attempted to install arch... I think I've done it, but all the tutorials said to skip installing the boot loader and install it manually from the live cd.
So basically I booted the live cd again, and did this:
grub-install /dev/sda3
but I get this:
/dev/mapper/../dm-0 does not have any corresponding BIOS drive
However, my compter works , and rEFIt detects OSX and Win7...
I really want to be able to use Arch, I'd appreciate it greatly if anyone can help me to get grub to work/or ger Arch to somehow boot alongside the other 2 OSes.\
PS. My computer is a MacBook Pro 15" i7 from late 2011.
Thanks!!
EDIT: Could it be because sda3 is ext4?

Self Solved:
Do not reboot after install, install grub directly after exiting arch installation.
