Hi, I bought Lion online and installed it. The installation seems successful now I have a log in screen with my name asking for a password. The problem is that I have never had a password and the previous OS let one log in by just hitting the enter key with the password box blank. Lion doesn't let one do that. The password hint box that pops up is also likewise blank. How do I set a password for my MacBook pro without being to get to the system preferences? I tried the suggestions of restarting holding down the options key and R and that did not give me the "terminal" option required to reset. The only four options I have are to reboot lion, go to a back up of thet old snow leopard version on a hard disk, search online, and one other option (I forget what). Please help.
