Hi guys. Nice site and these forums seem tremendous. Glad I stumbled across them. Long story short, during the 10.7.3 update, my Macbook froze at "moving files". Since I did a restart, I've been unable to get past the white screen. I've tried to do disk repairs, pram reset, safe mode, etc and every possible solution that I've read about over the last 10 hours. After being fed up with it, I decided to bite the bullet and simply do a restore back to as if I bought it brand new. I went and erased the HD and now I went to install the old Mac OS X disk that came with it but it says that I can't install it. Therefore, I'm left with no hard drive, can only boot and get the recovery HD when holding down option at power up, and it won't let me install the original Mac OS X that came with the system. I should not that I downloaded Lion pre-release so I don't have a copy of it or can't boot from the Lion disk (which is one reason I wanted to go back to Leopard). Can anyone point me in the right direction? I'm lost and feel helpless.
