I recently got my iMac back from repairs and found that the technician had installed ML over Lion on my previously installed SSD. I am in Vietnam and this kind of thing is pretty common here. I have a CCC clone (external) from a week ago with 10.7.5 and I cloned it back to my internal 1TB and it seems to function properly. My question is: Can I create a USB stick for ML if I have only the installed OS on my computer? I do not have the installation dmg. I have mixed feelings about this but I can rationalize it because Apple has made it effectively impossible for me to buy and download ML because I can only access the Vietnam Appstore and when there I can't buy anything because I only have US credit cards. If I could I would buy it without hesitation. I am also pretty sure that upgrades will not be available. I may clone Lion back to my SSD too but I would like to have a copy of ML on hand if possible.
