I erased the HD in Disk Utility (tried to erase the one with all the numbers but got the message "unable to unmount") and then used a disk to intall 10.6 but this didn't work, forgot the message I got but it wasn't allowed.  My goal is to go to 10.7 wich I purchased in the Appel store. Does anyone know how to do this?

iMac, OS X Mountain Lion (10.8.3)
