I have a MacBook Pro 13" that is having some serious issues while trying to install OS X from its original disks or my Lion backup. Problem: When trying to install OS X on brand new (Formatted with GUI partition and OS Extended Journal) WD Blue 5400RPM HDD I am encountering the spinning loading sign freezing after about 3-5 minutes of trying to load the disk. Solutions Tried: - Computer is reading both HDD & Disc (Holding option display both on boot) - Computer boots fine with old HDD in place - Tried a third HDD to rule out the possibility of a bad drive - Reset the PRAM - Reset the SMC - Boot from a USB drive - Tried my OSX Lion backup DVD - Tested both discs in my iMac to make sure they work - Use an external DVD drive instead of the built in super drive - Tried installing Lion on the HDD through my iMac, but when finished said that installation had encountered an error. - Tried booting into safe mode. It loads the bar and the bar then freezes shortly after loading is completed. - Got the installation working through my iMac and have a fully working brand new HDD with OS X Lion loaded on it, but still gets stuck. Not sure what else to do? Any suggestions?
