Sign-in coming up every time I try to install OS X
Hi,
I've encountered a problem when I'm trying to install OS X Lion on my MacBook. Every time when I select to reinstall Lion I get past the whole terms and conditions step to which I agree to and I get to the next step which is to select the hard drive to install the OS onto and this is where I encounter the problem.
When I select the formatted and partitioned drive it tell me to put in my Apple ID and password, but when I put them both in right it gives me a message saying that the item is temporally unavailable.
What I think is setting it wrong is this disk image that's called disk1 and has partition called Mac OS X Base System.
It might be the previous owners back up thats not letting me reinstall I don't know. If you can help me then I would be very great full.
MacBook, Mac OS X (10.7)
