I have NUC 3815 and due to sudden power loss, the system got down. When powered up (by pressing the power button), I see always GNU GRUB screen and not able to go further.
I'm using Ubuntu (Debian) with Kernel 3.13.0-30-generic.
Kindly help me for solving this issue.
Prem, usually this behavior is cause when there are more than one kernels installed. Please check this thread from an Ubuntu community Question #219067 : Questions : “grub2” package : Ubuntu
I could recommend you also to check which is the BIOS version install and try to update it to the next available version. Intel® Download Center
