I'm not quite sure I have totally understood you. Please correct me if I am wrong but this is how I've read your symptoms:
- MacBook not booting
- Plug in external hard drive, choose that as the startup volume. MacBook boots.
- Remove internal hard drive and replace with hard drive that has OS installed. MacBook not booting.
- Remove replaced hard drive, plug it in to usb port. MacBook starts up fine
Does the above correctly summarise the problem?
If it does, then the fault can only be one of two things.
- The SATA connector is not fully seated into the hard drive.
- The SATA connector ribbon cable is damaged and needs replacing.
The good news is that, obviously, everthing else in your MacBook is okay (logic board etc) else it would not start up when an external hard disk is plugged into the usb port.

yup, from my research I thought I'd probably have to replace the sata connecto cable. but I'm not sure my model is simple to replace. (late 2009 macbook uni body) I examined the cable and it seems to be built connected to the logic board rather than being able to simply unplug it and place another. I could be mistaken. do you know how hard or easy i'd be for me to replace it?
I appreciate the response

Here you go:
If you are comfortable using a screwdriver, it will be very easy. If, however, you feel apprehensive in any way then it's best to take it in to be done.

Thanks, I'm comfortable with screwdrivers now after moving my hard drives all over the place, once I find were to get a replacement connector I'll give it a go and let you know how it goes.

Update: before I asked this question, I had already ordered an SSD. It arrived today and I put it in the computer and it didn't see it. thanks to you showing me the sats cable could be removed I unpluged and pluged it back in and it read the ssd and installed mac os x 10.6 on it with no problem, I started it up adn shutdown a couple times and even moved about the house with it and it was fine. BUT
I went to work, I have to do alot pf walking before I can settle in and by the time I did I turned on the mac and got the empty folder icon.....its not seeing the ssd anymore......my problem probably is that my old connector can no longer take the amound of moving I do......so I'll probably by a new one and see how it goes........this was more of a downer than you can imagine.........
