I have windows 7 currently installed and I used EASEUS partition manager make another partition for mac os x. The problem is that it isnt detecting the partition when I go to install it. It works fine up until then. Ive tried many combinations for formating the partition from fat32/logical to fat32/primary and the same with ntsf. I even tried to leave it unformated. In the disk utilities when trying to install it also shows my hard drive to be 128gb instead of 750gb. I even tried gparted and to make the partition hsf+ but that didnt work either. Any ideas?

specs:
q6600
gigabyte ep45 ds3r
2gb ram
4870
750gb western digital caviar black
