Microsoft Windows 11

Good evening! While turning on my laptop it says that "Operating System Not Found". Of course, I have checked every parameter in BIOS, particularly, I checked order of boot. Also, I do have an OS - it was Windows 10 a couple of months ago and in August I downloaded Windows 11. The strange thing is that sometimes it works and sometimes it doens't. I haven't experienced such a problem for about a month but today it appeared again.
