Okay, so I picked up an old iMac G3 but it's only running 8.6 so.... I accquired OS X 10.3 install CDs, but I can't seem to burn the .dmg file or convert it to an iso file (in Windows XP). I have tried both MagicISO and UltraISO which are meant to handle dmg files but they both say 'Can't find the file or file isn't CD image file' Anyone have any ideas what I'm doing wrong? Any other converters or burners that may work?, EDIT - I have just managed to burn 10.3 to a disk but now the Mac is telling me 'This version of Startup Disk requires Mac OS 9.1 or later'. So I have to install OS 9.1 before I can upgrade to OS X? Is there not any way to directly boot and install from the CD as with XP? Ugh and everyone says Macs are meant to be easier to use than PCs! >_> Help! Ta!
