USB laptop screw up

 

I recently installed debian onto my 8gb usb memory stick or whatever that’s called. It worked on the desktop monitor that I initially started with but only a black screen pops up when I try my laptop. I go to the boot menu when turning on the laptop and select the usb option but nothing happens. What am I doing wrong?

 
   

well, i’m not sure what exactly went wrong. If there are multiple drives present the debian installer will ask where to install the boot-loader, if this was installed somewhere other than the USB you will not get a GRUB menu even though all the files for the installed OS are visible on the USB.
