Public bug reported: I had on acer extensa 2519, 2G RAM, 500G HDD windows7 and ubuntu 18.04 and boot them via grub2 legacy (switchable to efi). As it was slow I installed xubuntu and during installation it strongly requested efi system partition. S I created it and then the installation process failed as there was a conflict when it installed grub2.
