I would like to ask if anyone has used Linux ubuntu. I want to enter the bios menu and reinstall. But I can't, I've tried using the internal/external keyboard. Before installing ubuntu it was still safe to enter the bios menu. But when I use ubuntu, I can't enter the bios instead I enter the gnu grub. I am an Acer aspire 4752 laptop user. I usually use the f2 key to enter bios. But now it can't enter, even though my keyboard is not damaged. [Click the link below to see photos of my problem](https://i.stack.imgur.com/rZuLF.jpg)
