MacBook Pro not installing lion

Hey guys,

I recently tried to wipe my HD and reinstall OSX Lion again to wipe my computer and start again. But now i am having difficulty installing Lion again as when i reset my MacBook Pro it comes up with the internet recovery and the option to reinstall OSX Lion. Once i click on that option it says its verifying the update with apple, then comes up with an error message saying an error occurred while preparing the installation please open application again. Or something along those lines this effectively leaves my computer unusable as i cannot do anything else with it. Can someone please help with this?

Thanks

MacBook Pro (15-inch Mid 2010), Mac OS X (10.7)

You said that you wiped the drive. Did you reformat the drive as Mac OS Extended (Journaled)? When you boot into recovery mode click on the disk utility option. choose the disk and then erase it; make sure you choose the mac os extended (journaled) format. after that you should verify the disk. if there are any problems you should repair the disk. Hope this helps.

Could it possibly be because I had lion updated past version 10.7 and I am trying to revert back to 10.7?

I was reading the article that I linked to, and you might not have the right kind of internet connection. Maybe you can take it to an apple store and try the installation using their wifi. If that fails and you are polite and courteous the genius bar staff might even give it a try for you, even if you are not under warranty. Good Luck.
