I've been having a big problem with my Mini as of late. I'm running both Windows 7 and OSX Snow Leopard. At one time I needed to switch into Win7 and when I tried going back into OSX it would hang at the apple logo with a spinning cog (I think that's what people call it) underneath. I could still boot into windows, so I thought I'd make an Ubuntu disc to see if I could backup all my stuff via a live CD. None of those discs worked, and it was probably a mistake on my part, now windows won't boot. So, now I just figured I'd try to use the disk utility from the Snow Leopard install disk, as that's what I've been seeing online. No dice. I would select the snow leopard disc from the boot camp menu, it would hang at the apple logo, then turn into a cross. Now the same thing happens when I try to boot the snow leopard hard disk. I've tried safe mode, single user mode (keeps saying it can't "enumerate" a device or something), and booting the original leopard disc that came with my mini. If you need more info or need me to be more specific on something, I'll provide you with the information. If the hard drive is shot, or the whole Mini itself, it's fine. I really just want to know what's going on at this point.
