??? what is your question? xD
i run Ubuntu (or Lubuntu; Xubuntu) on machines WAY WORSE!
so if you have problems than your config is wrong!
I have verified the download, but I do not krow how to start ubuntu. Do I need to change config.sys?
I would suggest you to check this link about installing Bionic Beaver: https://linuxconfig.org/how-to-install-ubuntu-18-04-bionic-beaver
Also you can check here: https://howtoubuntu.org/how-to-install-ubuntu-18-04-bionic-beaver
Also here for the minimal server: https://www.howtoforge.com/tutorial/ubuntu-lts-minimal-server/
so you downloaded ubuntu iso and dont know what to do with it?
or do you want to run it in a VM?
btw - google is your friend!
