We have a laptop (specs below) that was running very slowly and now will not boot. Windows attempts to open, then tries to repair itself. After running for hours, a message was displayed that windows could not be repaired, When I clicked on details, the message was that the registry was corrupt (not sure if that was the specific wording).
I went to the Setup menu and changed the boot sequence to boot from the CD drive first, but that didn't work. When I go to the boot menu, the CD drive is not listed. Any assistance will be greatly appreciated.
Gateway laptop NV79
Windows 7 Home Edition
CPU: Intel Core i3 CPU, 2.13 GHz
HDD Model Name: ST500LM012 (replaced October 2013)
