I installed Ubuntu 14.10 on my computer on a tiny 20 GB Partition. I decided this was far too small, so I used GParted, resized the partition to an 80 GB partition, and Reinstalled the GRUB bootloader.
However, the next time I booted back into Windows, I was told
You may be a victim of software counterfeiting.
I tried activating using my Windows 7 product key (Which I couldn't get from the installation disk, because the computer was given to me by a friend, I used WinKeyFinder 2) but it's telling me "Your computer is not yet activated with genuine windows key."
I know this is incorrect because my computer was working properly just a few weeks ago! I talked to Microsoft support but they were no help. Now, I'm at my wits end trying to validate this product key because I want to install 64 Bit Windows on my computer, but I have no valid product key!
