I first tried installing W10 and it went fast and nice, without any kind of setbacks.Then I tried installing Lubuntu (selecting the "erase disk and install" option) and it crashes during installation, saying:
> The bootloader could not be installed. The installation command
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=ubuntu --forcereturned error code 1
I'm guessing that it's having a problem with the bootloader kek. How do I fix this? First time installing Lubuntu btw.
