I installed Win 8.1 in first drive C: and then attempted to install Fedora 19 in D: but after install, all packages in bootloader installation Fedora show the following error:

An unknown error has occurred this program has an unknown error 
you may report the bug below or quit the program file 

/usr/lib/python2.7/site-package/pyanaconda/bootloader",line 1550
in install raise boot loader error (bootloader install failed)

I have tried to install Fedora 19 with Win 7 Sp1 - Win 8 - Win 8.1 but all of the time these show the above error.

Most people on the internet said I must disable UEFI secure boot but I don't have any UEFI in my pc!

It seems my motherboard does not support UEFI. BIOS Information :

OS Name Microsoft Windows 8.1 Enterprise
Version 6.3.9600 Build 9600
System Model    P5K
System Type x64-based PC
BIOS Version/Date   American Megatrends Inc. 0704, 10/30/2007
SMBIOS Version  2.4
BIOS Mode   Legacy
BaseBoard Manufacturer  ASUSTeK Computer INC.

--- I dont have any UEFI Firmware Settings

I used some step by step guide from videos in Youtube but that didn't help me. What can I do?

Do you think I need Update my BIOS ?

Do you think I can not install fedora as dual boot beside Win 8 because my Asus`s BIOS is old and does not support Boot Secure ?

Can I have whole my installation error (bootLoader error) message into a text file ? that I share it here maybe help to solve mystery !
