Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I am getting above error when selecting any of options listed below.

Try Ubuntu without Installing
Instll Ubuntu

I have read many posts on this site with similar problem. But it is not helping me at all. 
When I click 'C' to enter into command line. It opens GRUB command line. SUDO and UPDATE commands do not work there.
Please help me that how can I fix this issue? Ty

A:

Please try following things and let me know if it works or not. 

Please make sure that you are installing Ubuntu 16.04.04 version instead of 16.04.01 from either bootable DVD or USB.
If Ubuntu 16.04 is still not working, try to install Ubuntu 14.04. It worked for me in past for same error.
