ok, i think this is in the right section - Can you reformat your computer without the startup disk?? i used boot camp to partion my mac, but i don't think it worked... as when i installed windows it formatted C and now i've lost my hard drive - which i have backed up, so not my worry, but i can't do any thing with it - haha, to quote someone else - i've turned my mac into an expensive paperweight... i have nothing to work with as i've lost half of my disks - the first one, i've got the second disk. I have the lepard disk that i updated my computer with - but it says that i can't install thing data there - probably because when i went into disk utility, it says that the format is 'Windows NT File System (NTFS)' if that means anything to anyone, i miss my mac, but yes, so does anyone know what i can do it fix it, cause i've done similar before, and i don't think my parents will be so accomidating this time....
