Well i was using Mint on dual boot with Witndos 10, so i wanted to remove Mint and install eOS with Windows. I've been trying to install for a long time using a DVD, but every time that i finish instalation a error message appears:
Unable to install grub in /dev/sda. This is a fatal error.
Then i reboot my laptop and a grub rescue screen shows up. I tryed a lot of options but none of them worked. When the system is being loading a message shows and dissapear:
Couldn't get size: 0x800000000000000e MODSIGN: Couldn't get UEFI db list
I don't know what to do. I've already done this tutorial, but when get the line:
grub-install --recheck --no-floppy --force
The terminal says:
grub install error doesn't look like a efi partition
At the moment i already gave up of trying.
My laptop is a Lenovo G400s, BIOS doesn't have secure boot just UEFI, but now i am using Legacy mode. This link shows how my setup Bios is like.
