I installed Xubuntu and can't find how to make a bootable usb on it to un-install Ubuntu [duplicate]

I installed Xubuntu and am not a huge fan of it.

I want Ubuntu back and can't figure out how to make a bootable usb on Xubuntu.

Please tell me my options

Solution 1:

You could also use "Startup Disk Creator". This comes with the standard Ubuntu desktop but you should be able to use apt-get to install it in other flavours.

sudo apt-get update
sudo apt-get install usb-creator-gtk

Solution 2:

No need to reinstall the OS, I feel that it is unnecessary. You can install various desktop environments in xubuntu.
Installing unity in xubuntu:

sudo apt-get install unity    

Installing gnome3 in xubuntu:

sudo apt-get install gnome-shell  

You can choose between various desktop environments while logging in
