A few days ago, I installed hackintosh on my Asus G60vx laptop.
I opted to install it on my external drive, and so far, it's been working great.

Recently though, I installed a second HDD in the laptop, and allotted 400gb to Windows file storage, and the rest I formatted as HFS+ and decided it would be the mac partition.

I planned to duplicate the external drive onto the laptop drive partition so I could boot off of it instead, so I installed SuperDuper! and did just that.

Unfortunately though, when I try to boot using the laptop partition, I receive the error:
"Missing operating system"

Any ideas on where I went wrong? Is there something I have to do to allow the drive to be bootable?

Thanks!
