Hi Guys. After some issues booting Elementary OS after a clean installation I had to change my BIOS conf to Legacy instead of UEFI. With the latter there was an error message of "cannot find the operating system". Thus, changing to Legacy was the only option I found to run Elementary. I just to want to ask for help to know how to fix this issue with my grub. I am not an expert in GNU/Linux. Many thanks. *Some additional information. Elementary is the only OS I'm running in my laptop right now. However, previously the laptop was using Windows that came for default with it. My laptop is Sony Vaio, S series.
