I'm clearly trying to free up storage space but I need to log into an administrator and when I do I just get a black screen with a cursor and now I am in safe mode and I can't click on anything I can't launch the start menu
Thank you for your message. What is the system model & operating system in question here?
Run a hardware diagnostic by following the video on this link & check if there is any hardware error.
If the system boots to the desktop screen in safe mode, it could be an issue with any of the application in startup or would be the graphics driver.
For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Sreejith R) & send a private message with the service tag, registered name & email address.
