I have a Macbook Pro 2008 aluminum 15-inch that runs on OSX snow leopard. Whenever I turn on my laptop, it boots up (apple logo and spinning wheel appears), and then goes into a loop of blue screens. I think the problem has something to do with the login process, because I sometimes see mouse and the brightness and sound icons appear, but it always fades away.
I tried doing fsck (command s), but the same problem's there. Safe mode also doesn't seem to work, unless I do verbose mode, but then again, it loops after the apple logo (grey screen). The recovery mode (cmd r) doesn't work at all. I tried pressing the option key but all i see is one disk, and that one still leads to series of loops. I also tried running the disk utility from my bootable usb but I don't know how to boot it. I tried pressing c and also tried the doing the option key thing. They both don't work, the usb doesn't appear at all. I tried resetting my pRAM, that doesn't help either. HELP! I just know that something is wrong with the disk, but I cant fix it because I can't go to recovery mode.
