UEFI Linux Grub Boot Fix

Rad. This OP Linux thread is from 2008 / Ubuntu 7.04.

On Ubuntu 16.04, you may get an UEFI / EFI install error. When it refuses to boot grub OS loader, you need grub-efi-amd64-signed from a restricted repository. Adding the repo along with an install would get your 1st run on that 100 emoji-launch.

Boot-Repair is a handy item, as this popped a dialog from a usb install ubuntu xenial studio (in relation to my error). In my case, I wiped the whole SSD as a 64 GB chopped in half was too light with free space.  Once the missing package was installed, my EFI partition installed and boot repair gave the sequential output script to Ctrl+Shift+V into a terminal.
Boot Repair sequence install the following into a terminal: 

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

This HP Pavilion x2 11″ LCD Tablet was a Windows 8.x and 10 device but the partitions were too small.  It was just prior a Windows 10 and Ubuntu Studio 14.04 x64 dual-boot.  This Studio distro works with the touch screen but lacks the features and lcd touch keyboard calls, without targeting app keyboard osd.
