I've tried to install Ubuntu 20.04 LTS on my Asus Zen Book 14 - model UX434F - in dual boot with Windows 10 without success... I've disabled both fast boot and secure boot. Then, I've launched Ubuntu installation using a flash USB and I've selected to install Ubuntu alongside Windows 10. Unfortunately, the installation fails when Grub is installed.
Unable to install Grub. This is a fatal error.
How can I fix this problem? I have any idea to solve this. I would appreciate any suggestion, thank-you in advance.
