After a clean installation of Elementary Loki, there is an error message during the booting that does not allow me run Elementary. "Cannot find any operational system". As I am not an expert, the only solution I found was change Legacy instead of UEFI inside the BIOS, and wallah! is working now.
However, although is working now I suppose something is wrong with my GRUB and I should fix it to be able to boot Elementary with UEFI. I would really appreciate any orientation about how to fix it.
This question it was already posted here Force UEFI installation? but unfortunately did not find a real solution.
*Some additional information: Elementary is the only OS I'm running in my laptop right now. However, previously the laptop was using Windows 10 that came in for default. My laptop is a Sony Vaio, S series.
