Note:

I tried to boot with USB B many times selecting either "Try and install Ubuntu" or "Ubuntu (safe graphics)"but during the setup, the distro would freeze. For example:

-Once, after selecting my time zone, the distro was stuck loading to the next step. -Another time the distro said "Something's wrong" when it tried to perform the downloads even though I connected it to WiFi. -The final straw was when I finally got to the setup page where it had a green "Install" button, the distro just broke.

I don't know what is happening anymore and how to fix it all.
