I was not a able to install Mountain lion. Got a message that my drive was not guild. I had 3 partitions, Mac HD, Boot Camp, and a Shared drive. I could not repartition, options tabs were grayed out. I deleted the Boot Camp drive and the shared. Left with one Mac HD drive. It was guild. I could not repartition this drive because it said it could not "unmount". I do not have my install/back up drive anymore. Not sure where it went. Now when I try to install Mountain Lion it just hangs up. Can't seem to reinstall from my time machine either. My machine is working fine otherwise. Any ideas how to approach this?

I have a 15" Macbook pro with all the current updates of 10.7.4.

So far so good. I was able to get logged in with the recovery drive i made. Are you suggesting that I erase the HD drive and then install lion or just install lion directly?

AS I said before as long as there is no data to save or you don't mind losing the data on Mac hd its definitely best to erase and then install because your chances of a smooth installation are much higher as there are no old configuration files to cause issues and I reckon if you install lion then upgrade to mountain lion then restore any data you should be fine I have done that with previous version heaps of times and had no issue good luck
