After not getting any response, I started searching about this issue on Google and came across this useful guide. First I enabled the graphics card and tried to detect it, but it did not work. Then finally I updated bios and after doing the methods perfectly, the problem got solved. The graphics card easily detected and I had no longer any issues while detecting the graphics card.

Anyway, thank you so much.
