I'm trying to install Ubuntu 18.04 on an Acer Aspire ES15 with UEFI. Originally, it was delivered with Windows 10, but now I don't want to use them at all. The intention is to have only Linux here without some dual boot. The problem is when the installation comes to the grub2
package.
I've found similar questions all around the different forums and also several methods to try. Unfortunately nothing helped me till now. I tried also different linux distros, but none of them worked. Finally I've found this similar thread, so I was able to install the system without grub
and then, when trying to install grub manually, it stopped me at
sudo grub-install --no-nvram --root-directory=/mnt
It says that the EFI directory can't be found.
I also tried to use boot-repair (recommended repair), but without success (now tried to install Linux Mint - same behavior like Ubuntu)
Here is the link for the boot repair summary: boot repair summary
Can somebody tell me what am I doing wrong?
