Wubi does not use GRUB to boot, it uses GRUB4DOS.

Please post the results of the boot info script so we can advise further.

There is a link at the bottom of my post with instructions.

Thanks.

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

by

but still upon reboot I got the following error


file:\ubuntu\winboot\wubildr.mbr

Selected entry could not be located because the application is missing or corrupt


I digged further and found
and bcdedit command shows

Above in bolded 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?
I am not clear as how can I know the identifier information for D: and try editing that in bcdedit.
Googling that I am not able to yet reach the correct way to find drive identifier so that I change entries in Windows boot loader.
