I wanted to know if i can install osx on an external hrad drive. I currently have the osx cd in my windows vista cd rom. I was going to run the install and point it to the hard drive. It wont let me run the extenstion on my vista. I would like to run osx anytime i plug this drive into a pc. I do have a g3 that has been installed with osx but its a pain to switch all the cables from on pc to another when i need to use the mac. Plus i could use the hard drive for work.
