Public bug reported: Installing Ubuntu 20.10 from USB Live failed at gru-install /dev/sda! I think problem has to do with UEFI/Legacy installation type. My system has already Windows 10 installed on /dev/sda2 and ubuntu 20.04 on /dev/sda7 in legacy mode, even if my system BIOS seems to support UEFI mode, I never used it! After the error if I open a terminal and try to enter command "grub-install /dev/sda" it return: ubuntu@ubuntu:/$ grub-install /dev/sda Installing for x86_64-efi platform. grub-install: error: cannot find EFI directory.
