cannot boot into Windows 8.1

[Chandu]

Here is the summary:
- Installed Ubuntu 13.04 64-bit on a pre-installed Windows 8.1 64-bit system.
- Grub is working fine and displaying my Ubuntu and Windows bootloader.
- But when I boot into Windows 8.1, the next screen throws me an error:

error: device format "ldm/xxxx...."
Press any key to continue...
