Then I have a proposition. If you don’t have any working OS in the system, go to the Live version of your Linux and run “Disks”. Then, select your drive partitions and delete them via the “-” icon. If that produces any error, then try the following. I think you may have some form of persistent storage - so it may work. Go to the terminal and type:
sudo apt install gparted
Then execute it to delete and format the entire drive. In that scenario, the drive itself will be clean.
