I bought the Student Upgrade for $30 last year to upgrade from XP to Windows 7. Since then, my hard drive has failed. I bought a new hard drive, and installed XP that came with the laptop.
How can I reinstall Windows 7? I have the Activation Key from the last time I bought it. I tried putting an ISO file on a DVD using this link Microsoft Fixes Windows 7 Student Edition Upgrade Problems
Windows 7 loaded up fine, but the Activation Key didn't work. Is there a way I can re-use my activation key from the first time I upgraded to Windows 7?
Keep in mind this is the Student Upgrade from Digital River (I believe it was Windows 7 Professional).
