I followed the procedure mentioned at Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported) on toshiba satellite laptop.

also tried the boot-repair and logs @ http://paste.ubuntu.com/6327398/

Its not booting to windows as well as ubuntu. It goes to grub command prompt.

When on initial screen it briefly shows error message as failed to open /efi/Microsoft/boot/grubx64.

Please advise.

EDIT : Secure boot in on and boot mode is UEFI Boot
