uninstalling linux lite from terminal

[Moltke]

Hi,
I need to uninstall linux lite from my hard drive but haven't had any luck so far. It is the only operating system on this HD. I have tried virtually everything but nothing seems to work. Is there anyone that could possibly help me uninstall linux lite from a terminal possibly?  I need in detail directions because I have tried searching but most of the commands do not work in linux lite for some reason. Thanks

You can't "uninstall" any OS, being it Linux, Windows or MAC, what  you can do is;
1. Install another OS over it; this will overwrite the existing HDD replacing the old OS with the new one.
2. Delete/remove the OS from the HDD; use something like dban https://dban.org/ burn to a USB, boot the live iso and follow the instructions. Or just use Linux Lite live USB, launch gparted, select the HDD and  fromat it.

Hope this helps!
