[Help] Need a big favour from you guys

I don't know if this is the place to ask this but I tried to install kali kinux on my usb drive sometime back only I did the installation as per some youtube videos (ignored some network problems) and the installation was fine and it restarted but then it just showd some black screen with _ . I thought it didn't work and took usb out and restarted it to run windows and now the same problem persists. What shall I do?
