Dual boot

[Celso Viana]

Dear All,

I had a setup with "Windows 10" and "Fedora 23" dual boot (UEFI). I
installed the "Fedora 24" on this machine and the installer failed to
detect the most "Windows 10". Does anyone know how to reconfigure /
reinstall GRUB to Windows appears in the boot menu?

Thanks

Does the EFI boot menu show an option for Windows?  Look in 
/boot/efi/EFI and see if there is a Microsoft directory there.

There is no Windows menu entry.

There is no Microsoft directory.

Thanks

Then you must have formatted the EFI partition during the install.  You 
could check the log files in /var/log/anaconda/ to verify that.  There 
have been several people with the same issue on ask.fedoraproject.org. 
The solution seems to be to get the install/repair iso file from the 
Microsoft web site and use that to fix the boot.

Maybe the installer created a separate EFI system partition?

Could you post the link that this command will show, as root:
sudo parted -l | fpaste

And just to clarify, the "EFI boot menu" is the menu you invoke from
the firmware at early boot (typically by pressing an F* button on the
keyboard).

Ahmad,

Here is the output of "parted -l"

https://paste.fedoraproject.org/454308/47673006/

Before I had the two OS for GRUB menu.

I see only one EFI system partition; so it must be what Samuel Sieb
said previously, the EFI partition was formatted during the
installation...

Hi Samuel,

I started the machine with a DVD of Windows 10 and could not repair or
restore Windows. Always returns error. Do you have any more
suggestions?

See the log file "anaconda.log".

https://paste.fedoraproject.org/474822/84241147/

Is it possible to save my installation of Windows 10 or will I have to
reinstall everything?

Thanks

How do you know that Windows is still there? I'd run a disk of GParted 
and see if the Windows partition is still there, and if it has anything 
on it. If it is and does, you might have
to run a Windows repair disk and re-establish the Windows boot. I don't 
know then how you'd get the dual boot back, altho Windows _claims_ you 
can dual boot with Windows.

UEFI makes dual-boot much easier, because neither OS needs to mess 
around with the boot loader of the other OS.  But GRUB can still boot 
Windows if you want.
