dual boot between ubuntu and centos

[oren tal]

I have installed ubuntu, then I installed centos.
I repatriate the hard.
Centos did NOT recognize the ubuntu, so I reinstalled ubuntu.
Now Ubuntu don't recognize centos.

I have the following partitions in my hard drive:
/dev/sda1 - etx4
/dev/sda3 - etx 3
/dev/sda4 - lvm 2
/dev/sda2 - extended
/dev/sda3/ - linux swap

How do I make ubuntu to recognize centos?
