Hi, So I own an acer lap top, I know very little about lap tops, and I had a virus on my lap top so I decided to do a reset, little did I know it would delete my operating system. So as of right now, I try to turn it on, and it says "Preparing Automatic Repair" and then it goes to "Diagnosing your PC" and then it says that Automatic Repair failed. From there I have the option to troubleshoot, reset again, or power down, or use a disk or usb. Although I have no disk, neither a USB, so I was wondering if I am done for, or if there is a way around this, using Command Prompt or something. Thanks for your help! Sincerely, Me
