OK I have looked at your profile, and unfortunately you have more than one computer and more than one OS

So, what is on the machine with the problem, and what sort of partition did you delete. Obviously I do not want to recommend something that won't work, or a desperation stakes "recover what you can" utility that will leave you with a real pain in the ass task of sorting out all your files again

Would I be right in assuming that your HDD is undamaged, and this is just something you have done by accident? The reason I ask is that data recovery tools tend to fall into two categories: Those that work on damaged media, and those that do not. You need to chose the right one, or you will only make matters worse or make a lot more work for yourself.

Cheers
