  • You're getting errors during the installation itself? Are you sure that your installation media is valid?

  • Yes during the installation It stop on the disk setup. and create errors above. No possible to format the disk. If can do that I can restart with a clean install

  • "No possible to format the disk" - can you elaborate on this? If your installation media is valid - your problem likely has to do with whatever is already on your PC. If you are trying to install Ubuntu alongside Windows - have you looked here: askubuntu.com/questions/221835/…

  • Because for me it^'s impossible to go the next step hard disk configuration. Originally, Kubuntu has been installed via the UEFI windows settings not directly by the bios option (usb selection).

  • Have you tried formatting your disk before starting the installer? You can do this easily with the "Disks" app in a live session ("Try Ubuntu")

Find a solution :

  • First reinstall windows
  • Reinstall Kubuntu
  • Create an EFI partition

Works fine now
