Hi there..

I have Windows 7 and Mac Snow Leopard 10.6.4.. but today when I tried to enter windows 7, gave error. I had to install windows 7 new, but it happens when i installed it, I did not see the dual boot to get back into the mac. if i put the installation dvd d mac, it shows me the disks on which you want to go and enter the mac, but without the dvd can not come, someone help me do it again dual boot?

Sorry my english..

Download GParted. Change the boot flag to the Mac partition. This should allow your boot manager to pick it up. If you can't get back into Windows try moving the boot flag back to the Windows partition and using EasyBCD. Hope this helps.
