Ubuntu Linux Bootable USB problems

[LegacyStijncat]

Hello, and thanks for reading this already!

 

I've made a bootable USB stick to install Ubuntu Linux on my second HDD partition.

Now, every time I boot the USB, eventually the screen becomes a small square in the top left if my screen.

Is there any way to fix this?

 

Thanks in advance!

 

 

(I've heard of Nomodeset, but I can't reach the options to enable that. Can you enable Nomodeset trough the normal USB files?)

You mean you can choose the USB from the boot menu and then when you press enter, the box appears?

For a small time, I can see the ubuntu logo.

But if I press install, or wait for too long, the screen minimizes and no further action can be taken.
