Hey, guys.

I have had Mac OS Lion for a while already. I installed Windows7 using bootcamp and all worked fine until today.

Little did I know, when I created the bootcamp partition, my Recovery HD disappeared. Today, my MacOS crashed so I had to reinstall it. The installer told me I cannot install the MacOS on the HD1(where i had my original MacOS). I shrunk the HD1, created HD2, installed MacOS on HD2, moved all my data to HD2, deleted HD1...and here is where I'm stuck.

I do not know how to extend my HD2 so that is uses the free space at the beginning of the hard drive. Is there any way I can easily do it?
