    You can fix your problem just by installing Boot-Repair and run it.

    First open a terminal window and type:
    Code:
    sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
    Hit Enter and then type:
    Code:
    sudo apt-get install -y boot-repair && boot-repair
    Hit Enter again and run the program.
    Please mark your thread as solved if you get a satisfactory response.

    First of all thank you very much for the reply.
    Boot Repair adds new entry "WINDOWS" in boot menu ..
    But when I click it..I get the following error..

    error:no such device: /EFI/Microsoft/Boot/bootmgew.ef
    error:file not found

    press any key to continue

    My windows 8 is on: dev/sda5

    You seem to have win8 installed in uefi mode.

    Did you install ubuntu in uefi mode too, or in legacy bios mode?

    From Boot-Repair post the link it creates when you run BootInfo.

    If you installed Windows 8 in sda5 in MBR it will not work unless you have another install of Windows in a primary partition. Or did you and then delete it (and Windows 8's boot files)? Windows only boots from a primary partition, NTFS format with boot flag. Grub does not need boot flag, but Windows boot files are all in that primary partition.

    I'm sorry there was a bug in the Boot-Repair version you used.
    Please :
    1) wait that all packages have a green check in this page: https://launchpad.net/~yannubuntu/+a...pair/+packages
    2) then update and retry Boot-Repair
