I am wanting to install Mac OS X Lion onto a Separate Partition on my HD. I want to be able to try Lion while still having Snow Leopard. Is this possible? If so, would I just create a new partition throughout disk utility, Open the Lion installer and be able select that newly created partition? Or, once partitioned, burn a Lion DMG to a Disk and do a clean install on the new partition? Will this erase my entire computer? i have TimeMachine Backup. Will a SL backup install on a new Lion OS? Lots of questions, but thanks in advance!
