Cannot dual boot to Windows 10

[djsolnok]

I just installed CentOS 7 on my Lenovo ThinkPad Yoga 14. Love the OS! However upon boot I do not have the option to boot to my Windows partition. I thought maybe something went wrong during the installation process so I went to re-install Windows 10. The recovery application detects the existing Windows 10 partition however. It just doesn't show up as an option in the CentOS bootloader. I only have boot CentOS 7 and CentOS 7 recovery options. This is what I have tried to do to see if CentOS could re-detect the partitions however the Windows partition never comes up in the output of the following command:
$ sudo grub2-mkconfig > /dev/null

My output is:
Found background image: /usr/share/images/desktop-base/desktop-grub.png
Found linux image: /boot/vmlinuz-3.16.0-4-amd64
Found initrd image: /boot/initrd.img-3.16.0-4-amd64
done

Also tried installing this package and re-running the command above.
$ sudo yum install ntfs-3g

Same result no Windows partition is found.

Could you please post the output of the following commands:

Code: Select all

sudo fdisk -l
sudo efibootmgr -v
sudo os-prober

Found linux image: /boot/vmlinuz-3.16.0-4-amd64

That's not a CentOS system.

Looks like Debian 8 / Jessie to me.
