I've got two questions: I received a Macbook Pro 17" that doesn't have a hard drive. I popped in my snow leopard DVD (MBP still doesn't have a hard drive) to see if it would boot. It does! I turn off the Mac, and, just to make sure, try it again. It does the usual startup chime, I hit option and select the DVD. It appears like it's going to boot just fine, but after a while it kernel panics. Each and every time. Is this because there's no hard drive in the Mac? There's no hard drive because I don't have the mounting bracket or screws to secure it in place. Could I just lay the hard drive on something inside the mac? So here's my questions: 1.) Why does it crash when booting from the SL DVD, but it worked fine once. 2.) Can I lay my hard drive on something inside the mac?
