[QUOTE="iambhu, post: 1470378, member: 193108"] In Target Disk mode, I was able to copy the "Install Mac OS," "Optional Installs," and "Instructions" files from the DVD (all that were visible), but when trying to open the "Install Mac OS" file, I got the error message "The application 'Install Mac OS' cannot be used from this volume...please use the application on the Mac OS installation disk." Next step? [/QUOTE]
