Full log of recover failure from running "rear -v -d recover"

Description of problem:
- Recover from rear does not work normally in RHEL 7.3 beta while it works well in
RHEL 7.2.

Version-Release number of selected component (if applicable):
- RHEL 7.3 Beta

How reproducible:
- It can be reproduced on any VM environments such as VirtualBox, virt-manager and so on


Steps to Reproduce:

In my test case, it could be reproduced in RHEL VM of VirtualBox on MacOS.

01. Created VM
02. Installed RHEL 7.3 Beta
03. Configured local repository after mount ISO installation image.
04. Install rear package
   $ yum install rear

05. Configure /etc/reare/local.conf

    OUTPUT=ISO
    OUTPUT_URL=file:///backup
    BACKUP=NETFS
    BACKUP_URL=nfs://192.168.0.XX/backup


06. Created backup
    $ rear -d -D mkbackup 

07. Confirmed if backup is created.
    We confirmed if backup data and ISO image are created in local /backup directory and backup directory in NFS Server.

08. Modified disk so that it's not bootable.
    $ shred /dev/sda

09. Confirmed that it's not bootable after reboot.

10. Booted with ISO image created at step 7)

11. Performing recovery job after selecting auto-recovery.

12. Confirmed that partition table and filesystems are recovered.

13. Found that installing bootloader is failed through error messages we uploaded on the case.

14. Confirmed that booting from local disk is failed.


Actual results:

With the following error logs, recover from rear ( rear -v d recover ) is failed.

RedHatEnterpriseServer/7 on Linux-i386 (based on Fedora/7/i386)
there is no code to install a boot loader on the recovered system or the code
that we have failed to install the boot loader correctly.

Please contribute this code to the Relax-and-Recover project. To do so
please take a look at the scripts in /usr/share/rear/finalize,
for an example you can use the script for Fedora (and RHEL/CentOS/SL) in
/usr/share/rear/finalize/Linux-i386/21_install_grub.sh or
/usr/share/rear/finalize/Linux-i386/22_install_grub2.sh

|          IF YOU DO NOT INSTALL A BOOT LOADER MANUALLY,              |
|                                                                     |

Expected results:

I expect that recover from rear would be worked well.
