starting from a different drive
I already submitted this question sorry I am new; do not see it anywhere.
My neighbor was using my computer and clicked on something that gave me an error message saying the computer had a virus; but with research this seems to be a scam to get you to pay for support. I am not seeing anything weird or unusual. But I used disk utility to check and it said the main hard drive needed repair. the other hard drives inside the computer were fine. It is kind of freaking me out. I got the message to restart the computer from another drive, so basically: can I use the other drives that are in the computer, or do I have to use a laptop and hold down control K or something? How do you do it?
