Hello ... I just had a problem occur on one of my family member's computer. I just had the computer set out perfectly and it worked fine for a few weeks. One day, he couldn't shut down his computer therefore he flipped the off switch and left. The other day he tried to open back his computer but there was this error msg saying i'm missing the /windows/system32/config/system file. Now windows doesn't load and its asking me to run the repair command from the disk. I'm not sure how to re copy the file back to my computer. /windows/system32/config/system file. I'm not sure how you work the repair option. Its on like dos mode. Not familiar with the commands ... someone help. Thank you
