The monitor of my notebook is broken and I want to install Arch-Linux on it. I have no problem to display the windows screen on an external monitor, but it doesn't show the initial screen where we choose the boot options. Is it possible to configure my computer through Windows for this to happen?
Your BIOS is probably set to skip the boot screen.
Click Start -> Right-Click Computer -> Properties -> Advanced System Settings ->Advanced Tab
Click on Settings in Startup and Recovery Section
See if there is a Check in Time to display list of operating systems (you can set the time in seconds)
