Yeah i think your right unfortunately but not having an understanding of mac's sub system I am at a loss of what might possibly be reset in order to boot from a disc or OS .

Being a system builder (windows machines) for a long time I am familiar with the bios of a windows machine. And if experiencing a similar problem it would only take a reset of the bios to get back to a boot able machine. So i am baffled on what a mac boots from or loads the initial input output from ? How does a mac know how to boot , or what devices are contained in the machine itself ?

Its almost like it is stuck between trying to load the windows boot and osx as it will recognize the windows disc but wont boot from it.



I still have the hard drive it came with it just trying to avoid the daunting task of removing the existing one , installing the old one in order to format the newer hard drive only to have to physically reinstall it again . I would have to purchase an adapter to hook it up to one of my pc's to reformat probably with symatec's partitioning program as it allows you to format a drive with macs file system hfs or whatever its called cant remember it right now . But this may have to be my last ditch effort to save this machine unless apple has a way to do it without removing the existing hard drive in order to format it . But here once again my lack of understanding apples sub system if it exist comes into play.

One last question , Why would you think that a leopard disc might provide a boot in relation to a tiger disc ? Is there a difference in the two as far as booting from the disc ?

thanks once again
