This question already has an answer here:
Basically I have a blank screen at the login after I have entered my password and have tried running in 2D and various other methods including downloading UBUNTU again and creating a bootable USB however none of these work since I don't have any permissions to run things in a guest account. I have tried and failed with the terminal entering an array of commands that all require a user not guest account. I can't make another USB since I have no windows PC and UBUNTU won't let me use any downloaded programme. I have just un-installed windows to be able to use UBUNTU and really have no idea where to go from here.
Thanks for reading lol
