Many thanks, nfoav8or, for your response. I'd love to provide you with the answers to all yours questions...truth is...I'm not very knowledgeable about all of this. I guess I need someone to walk me thru this, literally!

Let me answer what Q's I can...

I don't even know what SATA means, so I'm not sure if I have it. But when I Iook thru all the specs on Device manager, I can't find any mention of SATA, but IDE is mentioned several places.

I've already downloaded Leo4Allv3, and burned it to DVD. But when I try to install, it just keeps rebooting.

All your Q's about my system, I'm just not sure where to look to find the answers. When you advise me to "be sure I customize and select the proper drivers", I'm afraid I don't know enuf to do that.

I do have an external 120GB hard drive that I can use to install Mac, and I would eventually like to have both systems operating on my PC.

In short, I obviously need a walkthrough. I'd be most grateful if you could do that, but I can understand if it's too much to ask. I'm very keen to search the various sources for info on how to do what I want....problem is, I usually find that the material I find is already over my head!!

If you can provide me with step-by-step inst's on how to get the info you want, I'd greatly appreciate it. Meanwhile, thanks so much for your assistance so far.
