Reinstalling Windows 7 - Product ID


  • I had win7 on a VMare Fusion Partition on my Macbook Pro. I wanted to reinstall it using Bootcamp, so Win7 will have full access to all of the memory.

    I deleted the Fusion partition and thus Win7 as well. I setup a new partition using Bootcamp and started installing my existing Win7.

    Now it says the Prodcut ID is invalid.

    Can I get my product ID "re-validated" without having to purchase another copy of Win7?
