it's an OEM disk , it will install on any computer but you must have a COA code on your computer, If you use a non-version of your computer (ie a dell COA on a HP computer ) its 50/50 that it will work
If that is your restore disc I thought those are to be used to your computer only. Check microsoft before you get rid of this first. That is why the key code is on the computer.
Would you accept an already prepaid shipping label if so i would make it up an i could email it to you and you would be able to print it out yourself and then fold it in half and then tape it to the package you'd be sending out and it wouldn't cost you anything. i could even schedule a pick up so you wouldn't have to take it anywhere? if this would be ok please let me know?
Does it have the activation code on the package? If not it is usually a sticker on the side of the computer that has the number on it we would need the number to activate it after using the disk to install it.
