I am very familiar with Forums but this is my first post, Hopefully this is the right section. I have been a mac user for 5 years but I have come to a complete dead end with this problem I'm having. It's a long story but basically as of tonight I am now back to the ancient Tiger 10.4.11, I want to be back at Snow Leopard, (or at least Leopard). I am a final year uni student (dissertation), and as of tonight I have lost EVERYTHING, Photoshop CS4, VMware, Windows XP, Autocad, Bootcamp, all partitions, the whole lot. I am pressed for time so dont wont to 'make-an-appointment' with Apple and cannot afford to pay retail for physical OS discs when I can torrent them. My system WILL NOT upgrade/update, I have tried my housemates Leopard disc but my system says it cannot be installed, I cannot use Disk Utility, either booting from install disk or HD, everything there is 'greyed out' and 'unclickable'. Any Torrent client I download refuses to open. I am extremely stuck. Being on Tiger is extremely frustrating. Any help would be great - I have searched the internet for solutions to this problem but all require the use of disk utility or 'just put in Leopard Disc'.
