For some silly reason I decided to try running Windows 7 on my netbook instead of OS X. At this point I have decided I rather stick with OS X. However, after I restored the the drive by using a dmg file that I create using Disk Utilies, it will no longer boot directly from hard disk. If I boot from the USB stick then select the hard disk, everything seems to work fine. How can I get my hard disk to boot directly again?
When I restored the image, I had repartitioned the system with a MacOS Extended Journal partition and switched from MBR to GUID Partition Table. The newly created partition is of the same name as the original. I'm not sure what else I need to do.
