Looking for a method to deal with "missing operating systems_"

Today morning, my pc showed a message "missing operating system_" on the monitor.
Then, I went into the bios and made the setting back to default. However, it didn't work.
In bios, I could see that my boot SSD can be recognized by my pc.
Next, I tried to plug in an USB to reinstall window. However, it didn't work too.
So far, I am still finding a method to solve it.
Can anyone give me some advise?

    There may be several reasons:

    The SSD may be corrupted....you may check it's health with manufacturer's diagnostic tool.

    A partition that contains the MBR is no longer active.

    Some third-party programs or disk corruption can damage an MBR.

    It may be due to:

    corrupted SSD -check it's health with SSD diagnostic tool from it's manufacturer.

    Some third-party programs or disk corruption can damage an MBR.

    An incompatible partition is marked as Active.

    A partition that contains the MBR is no longer active.
