Grub only shows Windows Boot Manager and UEFI Firmware Settings

I installed fedora. But grub only shows windows boot manager and uefi firmware settings not fedora itself. This happened twice. What can i do to show fedora in the grub.

Lets see if I can pull the needed information out of my magic hat –
Nope, that did not work.

Not to be rude, but how would you expect us to know what you have done, how it was done, and what hardware you have with the total lack of information you provide. The only available information is that you are trying to dual boot with windows and have failed to properly install fedora twice.

Please provide a lot more information in the vein of what I noted just above and as much detail as possible so we may begin to understand what may have gone wrong.
