By preinstalling i mean that i installed 10.6 onto the drive with my MacPro. I did this because when trying to install it using my MacBook pro, the restart after the installation would hang in the grey apple screen indefinitely.
After i successfully installed 10.6 onto the drive in the MacPro, i put it back in my MBP and tried to boot with it and i encountered the same hangup in the grey apple screen.
I don't know what to do. I've been trying to figure this out for a few days now with no luck.
Surely, someone here can provide me with a solution.
