Cannot Install Ubuntu Mate Please Help out Please

I have made bootable USB flash drive of Ubuntu Mate 18.10 64bit. When I boot my pc from the USB flash drive then Ubuntu mate loads (boot logo appears). After that, it shows “Input Not Supported” always. What is the problem I don’t understand? Please help me out. Why is that showing this message & it’s moving the whole monitor screen? I have a 15.6-inch monitor with 1366x768 resolution. Help is really appreciated.

Also, I have Linux Mint & Windows 10 Installed on my hard disk.

It means that the system tries sends out a display signal that your screen does not support : either a too high frequency or resolution.

Espcially the F6 menu with the nomodeset option. Set it and then try to boot and install Mate…
