How should I get my PC working again?

Got an older Medion Akoya P6669 laptop, everything was normal until today. It starts, but then there's GRUB the whole time with a blinking cursor, I can't get into the boot menu with F8 or F10 and I'm pretty helpless and don't know what to do now…

What about ESC, F2, F12 and remove

Press everything at the same time, or try everything individually?

Thank you worked (F2)

go

Hey in your case the bios is F2 if nothing works, the biosbattarie may be empty

With pleasure. You too
