I checked the bios of my PC, the first boot priority is set to hard disk.
According to you I tried re-installing grub but as you can see from the codes I have posted, I am using a backtrack live CD because it is the only one I have. Backtrack has been completely discontinued so, I can't perfrom
apt-get install grub
I tried creating a live USB by unetbootin which comes pre-installed in backtrack but I think Kali Linux doesn't work with Kali Linux. So, what would you recommend to my situation?
