Hi, So I had my Windows Partition going via bootcamp until yesterday, when my younger brother used my Black Macbook (2.4 GHz? 2 G Ram) and like always he ruins it. So today I went to bootcamp assistant and I restored it, so the computer was 100% mac. Then, I made another 25 Gig Windows partition, and while I was installing that, my computer ran out of power, so it shut off. I put it into the wall, and then when I tried booting into OS X, it would get stuck on the Grey Screen with the Apple on it. The Windows Partition never fully installed, so that was gone too. I Then Put in the Leopard install disc, and I used disc utility to check out my disc. It advised that I erased my disk, and I did, after all, there was nothing too important on my computer, and I have time machine. Then, I put in the Leopard install disc again to install Leopard fresh, but it won't get to the disc. I hold Shift to go into safe mode and it won't do anything. I do command + s to get to single user, and it wont do anything. I hold C and it wont do anything. It always ends up with me at the gray screen. I tried holding Option to see what I COULD boot off of, and nothing showed...not even my install disc. I tried everything I could (PRAM, NVRAM, Took Out Battery..ect) but my limited 15 year old brain could not figure this Someone pleaaaaase help...my computer is like my baby and it is completely obsolete right now. I was also thinking about something with Firewire? I'm typing this message on my iMac, so I do have another one I can try to use as a host to get in and fix it. Thanks!
