If you cannot get into bios-settings, take or plug the hard drive off and boot computer using UEFI BIOS-boot USB
You can make the USB, writing the image using dd or simply copying using cp command. Notice that writing the image destroys all the contents from an USB!
An example about making the boot-usb:
sudo blkid ### tells the drives and partitions
If the USB is /dev/sdb, writing to the USB goes
sudo cp bios-boot.img /dev/sdb
If using dd, the process goes
sudo dd if=bios-boot.img of=/dev/sdb
