Windows Not Genuine After Partition Resize

I resized a partition (the boot partition) using gparted off a linux boot disk (should be the same as any other program, though) after removing a backup partition which was never used. I rebooted the computer, and it ran startup repair. After startup repair had finished, I rebooted again. This time it boots into windows and gets to the login screen. I can log in, but it comes up with "welcome", followed by "preparing your desktop". It then loads a temporary profile. From there, I tried to load the control panel to load system so I could input the product key, but it wouldn't load the control panel because of an error I can't remember - but it displayed something like this: "{random nums and letters}"how to make it boot from a permenant account?

PS. I have access to command prompt as admin, and regedit. Also, I have another windows partition which I might be able to boot from. I also have a linux bootable CD, if that helps (can move around files from there)
