Bad ribbon cable most likely.

Go to systems pref and select the internal drive as your startup if indeed that you want to use the internal as your startup disk. Do this after you copy the OS over to the internal drive from either a cd or cloned from another drive. Make sure you internal drive is formatted in GUID format.

I highly doubt it, your MB would not boot up and work from an external drive it that was the case. I believe it is your formatting of the drive. If it is not GUID it can not be used as a startup device in Mac OS.

Ok guys still in a dilemma it seems that the macbook can only really use the hard drive when its hook up by usb when i put it in the macbook it locks up constantly. Help please

Did you not read my answer to your post? I'll spoon feed it to you and say it again: it may very well be a bad ribbon connector between the hard drive and logicboard.

U may need to partition your hard drive, have you done that when you installed the OS?

What make and model hard disk are you trying to install in your MacBook Pro? (For example, a Seagate Momentus 5400.6).

 

[Bmoreguy03]

Seagate Momentus 750gb.. And the post about the bad ribbon that is a last resort because i would have to get that shipped off for the logic board and i would have to pay some where around $400

The ribbon cable itself can be had separately for roughly $40. Instead of instantly giving a negative to my post you could've looked it up.

I just did for you, aren't I nice?

Nowhere did anyone say you needed a logicboard. $40 is a rather cheap way to diagnose your problem, and if turns out that's not the problem, you can probably ebay the cable easily.

Thanks a lot for that im still getting use to this forum thing

 

[snaky69]

Heck, if you're handy with electronics and you know someone else with another mac, you can probably borrow their cable to try it out.

Does it say Mac OS X cannot be installed with the yellow triangle?
If it does say that, /Disk utility on the install disc/partition on main drive/drag the sizer up and down then back to normal and it should work.

ok thanks im actually going to try that because i do get that yellow triangle
