Hardware issue: If there is a problem with your hardware, such as a faulty graphics card or a malfunctioning monitor, you may see a blank screen.
Software issue: There may be a problem with the installation media or the installation process itself that is causing the blank screen.
To troubleshoot a blank screen during a Linux graphical installation, you can try the following steps:
Check the hardware: Make sure that all of your hardware is functioning properly, and that everything is connected properly.
