It seems unlikely that the EFI System Partitition was not properly
mounted. I booted successfully a couple dozen times before the grub
1.99-21ubuntu3.7 update. Moreover the EFI System Partition contains an
EFI/ubuntu/grubx64.efi file that shows a timestamp corresponding to the
grub 1.99-21ubuntu3.7 update. That would have been difficult to achieve
if the EFI System Partition was not properly mounted at the time of the
update.
This appers more likely to be some kind of path problem, since the
system WILL boot successfully when the grubx64.efi is explicitly chosen.

Title:
grub_efi_secure_boot symbol not found after update to grub
1.99-21ubuntu3.7
Status in “grub2” package in Ubuntu:
Incomplete
Bug description:
On a working HP ENVY m4-1015dx system using UEFI without secure boot,
the system is unable to boot into Ubuntu 12.04 from OS Boot Manager
following update to grub 1.99-21ubuntu3.7. The grub 1.99-21ubuntu3.7
menu appears correctly. However, selecting any ubuntu kernel generates
the error:
symbol not found: `grub_efi_secure_boot'.
The system will boot successfully into Windows 8 from the same grub
menu. The system also boots successfully to ubuntu from other BIOS
boot options: Ubuntu (WDC ...) or Boot from EFI File and then
selection of the file EFI/ubuntu/grubx64.efi. Either of these latter
successful boot options produce a grub menu that appears identical to
the earlier-mentioned grub menu, but these boot successfully. At least
two other individuals using different hardware have reported analogous
problems on the forums (ie. systems using UEFI but NOT secure boot).
These problems may depend to some extent on the BIOS, but they do not
appear to be unique to this particular hardware.
