    Since you dual boot, then I would recommend using OPTION THREE in the tutorial it is linked to in your post above. That link is the specific webpage that OPTION THREE is on to use.

    I have made a progress. I thought I followed the tutorial exactly but now the system boots to Safe Mode direct without displaying any boot menu. What could have been done wrong?
    This tutorial is the one I followed.

    I have found what I did wrong. Now it works.

    My understanding was that the pre-arrangement or adding Safe Mode option to the EBCD can only be done when the W8 is bootable, but that does not seems to be correct. I found it out while reviewing the tutorials.

    Thank you very much for your help.

    I am back again.

    It is still about adding Safe Mode option. The last time I started out using "elevated command prompt". This time I got into the command prompt by "command prompt at boot", but I could not change the drive from X: to C:, thus I could not begin the step 2.

    You don't need to change the drive letter to use that command.

    So, should I begin typing in as follows?

    x:\Windows\system32>bcdedit /enum /v

    Yep, you should be able to run it like that.

    It magically worked. I felt as if I fired a rifle in the dark but it hit a deer. Does it hit two deer if there are two? I mean if there are two W8 installed on the machine, is the Safe Mode added for each of them?

    Great news.

    Nope, the added Safe Mode to the Windows Boot Manager is specific to that one Windows 8 identifier. If you have a second Windows 8 installed, then it would need a separate Safe Mode added for it's identifier if you wanted one.
