    "Missing operating system" on launch


    Hello, I have been locked out of my Windows 10 Pc and need help getting back in. I was trying to open my bios to fix another issue with my USB ports so I went into settings, then to update and security, selected recovery, chose advanced setup and restarted my pc. I then chose troubleshoot, advanced options and then selected a control panel option. Then my pc shut down and when I booted it up it has a black screen with the text "Missing operating system".

    :)

    After updates Windows 10 says "Missing operating system"

    I have the same issue, and I followed your suggestion steps. After that, I can see C: drive, and Windows folder is there.

    Then I rebooted the computer. But I still have the missing the operation system issue. Any suggestions?

    Thanks.
