installed Linux Lite - only get GNU prompt

[misterbela]

I only want to use Linux

If there is nothing you need on the old set up it will be better to get your system to boot the live media again so that you can re-install Linux Lite from scratch rather than trying to fix the current set up.

Hello,
I'vd tried to re-install Linux Lite several times before I started this forum request. Have tried several times to do a clean restart to install, but the laptop will not recognize or does not want to recognize the USB stick. I have the laptop directed to read the USB first when booting up. However, the laptop first shows the Toshiba request to enter the correct date (and I then have an  option there to select boot up from USB), save changes, and then it simply goes to the Grub prompt. Still stuck at the prompt.
