At first I tried dual booting from a fresh Windows 11 install and no dice, after Ubuntu 24.04.2 LTS is installed, it jumps straight to Windows. Even manually selecting Ubuntu from the BIOS boot menu does nothing.
Then I tried installing Ubuntu alone without windows as a fresh install. Ubuntu boots, but without grub menu.
My computer is an Ideapad1 14IGL05, CPU: Intel N4020, 4GB RAM
