Ok I did some hit and trial and then bootinfo script gave following
http://paste.ubuntu.com/716700/
Above is result of bootinfo script.

I had copied my ubuntu folder from /dev/sda2 to /dev/sda5 so I made
corresponding change in grub.cfg

replaced uuid

     E4ACAFF5ACAFC082
by
8E9E86339E86143D
but still upon reboot I got the following error

file:\ubuntu\winboot\wubildr.mbr
Status: 0xc000000f
Selected entry could not be located because the application is missing
or corrupt


I digged further and found
and bcdedit command shows

C:\Windows\system32>bcdedit


Real-mode Boot Sector
---------------------
identifier              {913c60b1-d90e-11e0-9e01-869473ab8036}
device                  partition=C:
path                    \ubuntu\winboot\wubildr.mbr
description             Ubuntu

Above  is wrong as when I copied every thing from C: to D: so here
also the entries should change.
What possibly more do I need to do now? Apart from changing grub.cfg?
