Lifebook E756 „ Bootable device was not found“

[Viviana]

Hello all,
I'm not a computer expert, so if you need additional information, just ask.

I have had a Lifebook E756 for about a year, and it has always worked fine.
I wanted to delete the temporary files with the program “CCleaner” that I usually use. I always delete only the browser files.

Suddenly the screen went black, and I got the following error message “Warning Bootable device was not found”. After pressing “Enter” the “boot menu” appears.
What can I do to solve the problem?
Thanks in advance
