Description of the problem:
The problem is Fedora's implementation of GRUB2. It doesn't play nicely at all with any Other OS in a UEFI environment. One must use another distribution to write GRUB. it is possible to install Fedora without writing boot information. That's what one does running other Linux OS and Windows as well because Fedora's GRUB2 fails constantly. It means that one has to dip into the other OS occasionally after updating the kernel in Fedora to re-write GRUB2, since it seems far more reliable that way.

Version-Release number of selected component (if applicable):
GRUB2/Fedora25

How reproducible:
Always

Actual results:
Fedora's GRUB2 fails to boot other Linux distros/kernels in GRUB2 list

Expected results:
Fedora's GRUB2 successfully boots other Linux distros/kernels in GRUB2 list

Using another distribution to write GRUB didn't help in this case: http://www.forums.fedoraforum.org/showthread.php?t=300131

(unresolved since August 2014)

Legacy BIOS boot is somehow affected too: http://forums.fedoraforum.org/showthread.php?t=312241

In other words, what is written in the above link is the following: anybody can perfectly boot from the newest version (grub2-2.02-0.38.fc24 or grub2-2.02-0.37.fc25 respectively) WIN OS (in this case WIN7) with grub entry:

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager (on /dev/sda2)' --class windows --class os $menu
entry_id_option 'osprober-efi-D601-A70F' {
insmod part_gpt
insmod fat
set root='hd0,gpt2'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2 D601-A70F
else
search --no-floppy --fs-uuid --set=root D601-A70F
fi
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}
### END /etc/grub.d/30_os-prober ###

Am I getting this correct? 

Thank you,
_nobody_

Comment 4 Fedora End Of Life 2017-11-16 18:35:13 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bug reports from releases that are no longer maintained.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.

Comment 5 Fedora End Of Life 2017-12-12 10:17:04 UTC
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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.
