My Asus X555l laptop is facing disk booting issue for quite a while, sometimes whenever I boot up my device it shows the following message - " Reboot or select proper boot device", so I check the BIOS and it doesn't show my hard disk in "boot option" or in short my laptop cannot detect any hard disk.

So I am left with 2 options-
1.) Continuously restart my laptop until it boots up as it should.
2.) Beat the laptop's base gently which is the last thing I do.

I don't know where lies the problem, but the good thing is that the device is still under warranty.
So should I go to the retailer for repair/exchange or is there any other general fix that you guys can help me out with and save me the trouble to go there?
