Douglas, when booting from usb, does the grub2 menu screen appear? If it 
appears, go to command prompt ('c') and
type "ls"; note if it is (hd0,1) or (hd1,1).
If both appear, your hd is 'not dead' technically, then type
"search -f /boot/grub/grub.cfg" and note output again.

then type
grub>linux (hd0,x)/vmlinuz root=sdax
grub>initrd (hd0,x)/initrd.img

note: if (hd1,x), then change sdax to sdbx

When booted up go to terminal and type
sudo grub-mkconfig

recheck output that the correct (hd0,x) is used as similar to your 
search and check uuid number of usb stick to be sure with fdisk.

If okay, then type
sudo grub-mkconfig -o /boot/grub/grub.cfg

Hopefully, that won't be necessary.

Whey do we live? To prove that some things in nature have no purpose. :)
