I am a new user to Ubuntu. I am having a Lenovo Y50. I recently dual booted windows 8.1 with xubuntu 14.04. My problem is the laptop upon starting is going into grub>prompt rather than going into the grub menu. I am being required to type normal in the grub>prompt and then it shows me the grub menu to boot into windows or linux. I am not sure what has to be done. Please help me out.
The command sudo-update grub gives output as follows:
chandra@RamaKrishna-PC:~$ sudo update-grub
