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?
