I bought a computer a while ago which came with Vista and a free upgrade to 7 home premium.

I had to put professional on the one I bought.

Now I have a Dell 7 upgrade disc with a key, but am too afraid to install it on my gf computer which is an HP. She has vista home premium.

I have read conflicting reports on whether or not it will work.

Microsoft and Dell proceeded to tell me to not risk it and urging me to buy a copy from them at their overly bloated price. (I can buy an upgrade for her for $65 right now - student, but am really trying to save that especially since I have the discs in front of me)

If I CANNOT install it, can a person with a Dell install it?

Thanks!
