I have a weird problem - a Mac that won't boot, but the drive was in good enough shape that I could clone it over to a new drive. So now I know the hard drive is fine, but it still won't boot. I have 10.7 on the system, and it just spins forever while booting. I tried a safe boot, no dice. Swapped the RAM, no help. I figure, what if I could just upgrade the OS? I have 10.8 on a bootable drive and could certainly install it, but I have a lot of settings and programs that I don't want to restore. Is there any solution? When I told it to install 10.8, it told me that the target drive was not Journaled, and that i should enable that in disk utility. I see no way to do that without reformatting. Any suggestions? Thanks! Edit: I also know it would be easy to do this if I had a TM backup - I could install 10.8 clean and then restore from the TM backup. But I don't have that. Is there a way to use the existing HD as if it was a TM backup in that way? I've always found it weird that Apple would allow the TM backup to be so useful while the actual HD is less so.
