Jeg ville prøvd help, quit eller exit hvis laptopen normalt fungerer bra og ikke noe nytt er endret.
Dette bør enten gi deg en meny, eller fortsette til en.
grub er løsning for å boote enten windows eller ubuntu, så du er ikke inne i linux her.
Bruker ikke dual boot selv.

On many installations today, GRUB hides this menu unless you press a key.
In a normal boot, you use the up- and down-arrow keys to navigate through the menu and then select your desired entry by pressing Enter. On Linux systems, GRUB then loads the kernel and initial RAM disk and passes control of the computer to the kernel.
F2 under oppstart sender deg normalt inn en setup vs. boot rekkkefølge og alternativer,
men ikke endre noe her hvis valgene fortsatt virker rimelig.
