Issue with loading Windows 8 after installing Ubuntu 13.04

[Harish_Keri]

Hi,

I installed Ubuntu 13.04 over pre-installed Windows 8 (from Dell). I do have backup and recovery disk for windows 8.
The problem now is that the Windows 8 OS is not recognized by Grub during boot; and I can now only login to Ubuntu.
Also, the recovery disk does not find any issues with Windows OS or the Windows boot loader.

I tried boot-repair, update-grub; but it still is the same. Please find the details in paste bin @ http://paste.ubuntu.com/6217832/

Thank you in advance for your help and advise.

Welcome to the forums.
When you wrote Ubuntu over Windows you erased Windows. Is that not what you wanted?
It still has a couple of Windows boot files in the efi partition as it uses the same efi partition, but you have no Windows install nor any recovery partition on your hard drive.
