You can still access the bios in Windows 8/8.1 but you cannot access safe mode by tapping f8 key & to acess bios the key button is different in every computer in some it's f2 , in some it's delete etc

Bios key for my laotop is f2 & f12.I know that.
But nothing happens if i press f2 or f12 due to
windows 8 fast boot feature.

I know what you mean I had to restart my neighbor's pc 2/3 times to access it due to it booted fast so when you turn on the pc quickly tap the key of bios in your laptop if your lucky you might be able to access it
