I've finally decided to have a go at fixing the problem where the Windows 8 option disappeared from my GRUB menu when I upgraded from F19 to F20.
Working through various Google responses I've found that i had a load of stuff missing, including
* .mod files * /boot/etc/EFI/Microsoft
I installed grub2-efi-modules-2.00-27.fc20.x86_64 and then copied ntfs.mod and parted_msdos.mod to /boot/efi/EFI/fedora/x86_64-efi/ which got rid of some of the errors
I then mkdir /boot/etc/EFI/Microsoft/Boot and copied bootmgfw.efi from /windows/Windows/Boot/EFI/bootmgfw.efi to /boot/etc/EFI/Microsoft/Boot
However, although I've fixed most of the error messages, I've still got the error:
efi: file `/EFI/Microsoft/Boot/bootmgfw.efi` not found.
I'm now stuck. Has anyone got any suggestions what to do next?

There's an awful lot going on here. And to vent, I'm going to start out by saying dual boot sucks. It's not you, users are sane, and dual boot support on Linux just sucks. OK...

This suggests the computer does not have Secure Boot enabled, because Fedora's GRUB has never support UEFI Secure Boot chainloading of the Windows bootloader. The fact the GRUB menu entry used to work, and now doesn't, suggests some other problem.
parted shows (sda4 is the Win8 partition, sda5 is the recovery partition):

The EFI System partition being fat16 is suspicious. It's supposed to be FAT32 per UEFI spec (removables can be FAT 12, FAT 16, or FAT 32 depending on their size). Anaconda however, doesn't force mkdosfs to create FAT 32, it leaves it up to mkdosfs defaults. And based on the size of the ESP Anaconda creates, mkdosfs formats it FAT 16. It's possible your OEM Windows installer likewise semi-improperly formats this FAT 16.
That it's FAT 16 isn't likely a problem, except that if it was reformatted, and not repaired by Windows startup repair yet, might explain why you're not able to boot Windows.

The insmod part_msdos is wrong. It should be part_gpt as this is a GPT disk.
I strongly advise not using 40_custom for this. You should let grub2-mkconfig find Windows, and create the proper boot entry from scratch.
set root='hd0,msdos2' if [ x$feature_platform_search_hint = xy ]; thensearch --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos4 --hint-efi=hd0,msdos4 --hint-baremetal=ahci0,msdos4
More msdos stuff which is wrong...

Is this the correct UUID for the Windows volume? Check with blkid. grub2-mkconfig will get this right, which is why it should be used instead of a static configuration.
./efi/EFI/Microsoft/Boot/bootmgfw.efi
This being the only thing in /boot/efi/EFI/Microsoft is perplexing. I'm expecting a lot more stuff in here than this. So yet again I wonder if maybe this EFI System partition was inadvertently formatted when doing a Fedora installation? It's not difficult to accidentally delete it, I've found.
But the fact is that you're not seemingly getting an error from this OSLoader, you're getting it from GRUB not finding this path which suggests the menu entry is malformed somehow.
Suggestions:
- Move /etc/grub.d/40_custom out of that directory so it doesn't get used, but is still retained in case you want to revert. - run grub2-mkconfig -o ~/Downloads/grub.cfg
post that grub.cfg somewhere or maybe it'll all paste into the mailing list which is fine too, I want to see the whole thing *unless* it doesn't have a Windows menu entry listed in it. If it doesn't then I'm going to guess that /etc/default/grub has os-prober disabled. If so that needs to be commented out and you need to rerun the grub2-mkconfig command.
Hi Chris,
Thanks for this. Just had a fantastic honeymoon, but now back in the real world and onwards with trying to fix this.

The folder /efi/EFI/Microsoft did not exist, which tends to confirm your suspicion that the the partition was reformatted during the upgrade. I manually created the folder and copied bootmgfw.efi from \Windows\Boot\EFI\

After advice from Chris I've created the Windows recovery USB stick from
http://windows.microsoft.com/en-us/windows-8/create-reset-refresh-media
and run it choosing the system repair option. I now have a working Windows 8 system on my laptop.
Unfortunately, it now boots straight into Windows and doesn't show the GRUB menu.
If I press <F9> to get the boot menu I can select from
OS Boot Manager Fedora (STT000LM014-1EJ164-SSHD) Boot From EFI File
OS Boot Manager takes me into Windows Fedora then shows me the GRUB menu and lets me boot Fedora
If I go into the BIOS menu and look at the boot sequence, OS Boot Manager is at the top of the list, but there is no other option that would make the Fedora / GRUB option the default. The full list is:
OS boot Manager Internal CD/DVD ROM Drive USB Diskette on key/USB Hard Disk USB CD/DVD Drive
Having booted into Fedora I re-ran
grub2-mkconfig -o ~/Downloads/grub.cfg
hoping that it would now include WIndows, but it still does not. This means that even if I get GRUB to be the default boot loader, I'll lose Windows again.
Can anyone suggest where I can go next?
//boot/efi/EFI/Microsoft/Boot now also contains BCD and BCD.LOG files as well as bootmgfw.efi

On a new Dell XP 13 I had for a bit in January, it had two F keys to use. One was for setup which is where the boot order could be permanently changed. Another one was for just one-time boot and was not persistent. So you'd need to dig around to find an option to make it persistent. Or you can do this from within Fedora using efibootmgr. So you'd do:
efibootmgr -v And then you'll see a BootOrder, and you can man efibootmgr to find the proper flag for changing the boot order, and make Fedora first in the list. But before you do that...

Clear+reset the terminal window. Then do: bash -x grub2-mkconfig
Copy-paste the entire window results into a (gedit) text doc and post a URL for us to take a look at it; it won't fit in the mail list. And also post the contents of /etc/default/grub - this will fit in the mail list.
Right, attempt 2.
As I started to say, thanks for the help Chris. The log file has been posted to:
http://www.stainburn.com/grub2-mkconfig.log
Now that the Windows side is working again, I'm wondering if it's worth biting thr bullet and doing a new clean Fedora install. At the moment I'm stuck with F20 as Fedup has decided that there are too many problems to allow me to upgrade to F21.
Do you think that doing a clean install to F22 would fix the problems, or make them worse?
++ GRUB_DISABLE_OS_PROBER=true
This is why it's not making the Windows entry. I mentioned it previously. So comment out that line in /etc/default/grub and then rerun grub2-mkconfig -o ... to make a new grub.cfg in the proper location.

Hi Chris,
Sorry I missed that. It's now included a chain loader entry for Windows, included below.
As you suggested, I tried looking at the man page for grub2-mkconfig. Unfortunately, I don't have that man page installed so I tried googling it. The search pointed me to
https://fedoraproject.org/wiki/GRUB_2
which has only succeeded in confusing me more. Based on the generated config file below, am I right in thinking that all I need to do to get GRUB to work and to allow me to boot windows is to:
grub2-mkconfig -o /boot/grub2/grub.cfg
Assuming this is correct, I still need to work out how to get the laptop to boot GRUB instead of the Windows OS Boot loader.

Hi Chris,
Sorry I missed that. It's now included a chain loader entry for Windows, included below.
As you suggested, I tried looking at the man page for grub2-mkconfig. Unfortunately, I don't have that man page installed so I tried googling it. The search pointed me to
https://fedoraproject.org/wiki/GRUB_2
which has only succeeded in confusing me more. Based on the generated config file below, am I right in thinking that all I need to do to get GRUB to work and to allow me to boot windows is to:
grub2-mkconfig -o /boot/grub2/grub.cfg
That's for BIOS systems. Fedora's GRUB does a screwy thing on UEFI putting it on the EFI System partition, so you have to do:
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Assuming this is correct, I still need to work out how to get the laptop to boot GRUB instead of the Windows OS Boot loader.
efibootmgr -v ## to list the boots efibootmgr -o 0000,0001,0002....etc ## to explicitly set the order, use the boot numbers separated by commas.
Or do it in the firmware configuration/setup UI.
### BEGIN /etc/grub.d/30_os-prober ### menuentry 'Windows Boot Manager' { chainloader /EFI/Microsoft/Boot/bootmgfw.efi boot } ### END /etc/grub.d/30_os-prober ###
Yeah that's very clean. There's no set-root or search root or search uuid or anything because the Windows bootloader is on the ESP, which is also the GRUB root, and therefore there's no need to change the root or search for a uuid to find the Windows bootloader. The path is relative to the GRUB root.
And just FYI the Fedora NVRAM entry (revealed with efibootmgr -v) doesn't point to GRUB, it points to shim.efi. That's normal.

Chris, your advice has been priceless and spot on.
I now have a laptop that boots into the GRUB memu, and have working Fedora and Windows options.
All's right with the world - at least until I try to upgrade Fedora again.

Yews, I believe that is correct. But just to save yourself some grief, make sure that ntfs-3g and ntfsprogs are installed BEFORE you do that.

ntfs-3g is included by default in Fedora Workstation, but it's not needed on UEFI installs for os-prober to find the Windows bootloader because it's located on the FAT 32 EFI System partition. On BIOS systems, the Windows bootloader is on an NTFS volume, hence the dependency on ntfs-3g. And ntfsprogs is deprecated since Fedora 15.

also, did you run a web search of;

are possible answers to your problem.
among responses, there is also mentioning that 'fat' partitions must be type 'fat32', not 'fat16'.
did you create the 'ESP' as 'fat16' instead of 'fat32'?

/boot/etc/EFI doesn't make any sense.

Got it. So the problem there though is /boot/efi/ is a mount point that only exist once Linux has booted and everything is assembled.
From the perspective of GRUB it does not exist yet. The location is
actually a specific drive + partition + path. The drive, partition, and partition scheme is what makes the root to look for hd0,gpt2 in GRUB speak, and the path is just /EFI/Microsoft/Boot.
But the grub.cfg has this wrong it either looks for hd0,msdos2 or hd0,msdos4, but what ought to happen is fall back to looking for the FAT volume fs UUID. But we don't know if that's correct either, especially if the ESP was reformatted since the 40_custom entry was created.
So that's why I'm suggestion just remove 40_custom, and let grub2-mkconfig create the proper Windows menu entry from scratch. It should find out all of these things and just work.
