Maybe you guys can help me figure this one out. I have Dell XPS L702X. I just finished a clean install of Windows and after restarting I got the message "Operating System not found". I powered off the computer and turn it back on and it went to Windows like normal. I tried to use restart again but I got the message another time. The problem seems to only happen when i restart the computer but not when I power it on.

You got more than one HDD/SDD?

If you go into the bios and check the boot order of the drives, chances are it's trying to boot from the wrong drive or a USB or something.

It's a single Hard Drive. I checked my bios and made sure that the Hard Drive was listed first in the boot priority. I'm not sure if it's fixed, but I unplugged the wireless keyboard/mouse usb dongle and it rebooted successfully. Going to try again and see if I get the error message.
