Hello, this is a problem that I have been having and cannot further continue mac usage until it is fixed. You must carefully read the following passage in order to understand my situation. Thanks in advance . I have put Mac OS Lion on an external hard drive. I do not have administrator on it, there are no other users, hence there is no administrator account on it. So I cannot change any settings in preferences. So I cannot boot off my internal regular hard drive with 10.6.7 on it, while on Mac OS Lion. Unless of course I hold option while at the white startup screen. That gets annoying. So when I am on my regular internal hard drive with SL, and I restart for an update it brings me to my external hard drive, Mac OS Lion. I want to fix this! I want it so I always boot off my internal hard drive! I don't even want the other Mac OS Lion boot anymore. So... The problem is my primary hard drive is an external one that I do not want to boot off of regularly now. I cannot change that because I am not administrator on that. I can still boot off my SL when restarting and holding option at the white screen but don't want to have to do that anymore. Please help, sincerely ClearRPG.
