My MacBook do not boot in Sata, just in usb drive
I have a problem with my macbook, when turn on, he show gray screen without apple's logo and stay in this screen for hours, if I put the install disk he don't recognize the hard drive inside, just in usb drive. I tried replace the hd for other, repair of disk, repair permissions of disk and disk install, but the problem remain.

This will solve my problem?
Is this a good question?
