I'm learning how to use Ubuntu Server, and after making my first install i realized that my partitions weren't correctly set up. It's way to complicated to fix now, and I regret not using my entire disk, so I want to reinstall everything from scratch. I don't care about saving any data or settings or anything.
This might sound silly, but the problem I am having now is simply accessing the live disk again. Now that I have successfully installed Ubuntu Server, every time I try to boot the Live USB, it redirects me to the installed version on my disk.
How do i bypass this and simply reinstall Ubuntu Server again?
