I have four install dmg files for mac os x tiger. They are labelled Disc 1 through 4. about 2gbs in total. I have these files on my PC. I have burned so many different copies of them but none of them boot on start up. The install app opens fine in mac os x (10.2.8) but when the dialogue asks me to restart...well it just reboots into os x again.... I have burned the first cd (Disc 1) with different programs and by using different methods but no luck. I am wondering is this installation suppose to be compiled into a dvd? before I can burn it??
