Please Help. Ive searched through the forums for days & cannot find the correct answer.I have an early 2011 MBP 13". It originally came with SL. I have misplaced the original disks. My hard drive recently failed. I purchased and installed a new blank one. I obtained a DVD copy of Lion ( which did work installing on another laptop), I get to the installer but it will not install. I went to disk utility & formatted the HD - extended journaled. When i go back to the main screen & click instal Lion,I get the spinning Beach-ball, it stops & nothing happens. any ideas? Any help is appreciated? Thank you
