Description of problem:
grub2-mkconfig generates config file with all entries listed twice.

Version-Release number of selected component (if applicable):
2.02-0.38.fc25

How reproducible:
I generated two grub configs: first for BIOS and other for UEFI. Because i didn't know which interface my computer is using after motherboard replacement/ Turns out it's legacy UEFI, which is equal to BIOS. Then i uninstalled the grub2-efi module and removed UEFI config file.


Steps to Reproduce:
1. Generate config for BIOS:
grub2-mkconfig -o /boot/grub2/grub.cfg

2. Generate config for UEFI:
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

3. Uninstall grub2-efi
sudo dnf uninstall grub2-efi

4. Remove UEFI config file
sudo rm /boot/efi/EFI/fedora/grub.cfg

Actual results:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Comment 1 Fedora End Of Life 2017-11-16 19:03:23 UTC
This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '25'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 25 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26
is no longer maintained, which means that it will not receive any
further security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
