Was running OS X 10.10.5. Deauthorized iTunes. Signed out of iCloud. Went to internet recovery, then erased Macintosh HD from disk utility. Then clicked reinstall Lion. It went through the download and then popped up an error saying it couldn't finish and that I should run the app again. I tried it twice more and still the same error. What did I do wrong(I thought I followed the instructions pretty well)?
