Public bug reported: 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.
