This question already has an answer here:

i have window 7 and Ubuntu 10.04 in same partition (with Wubi) and ubuntu 12.04 on separate partition of my Dell Inspiron 4030 laptop. I installed Kaspersky antivirus and scanned my laptop, but after reboot I could no longer boot into the Wubi 10.04 install.

Starting Windows didn't succeed. The reason may be changing software.
To solve this problem:
1. Insert installation disc of Windows and reboot pc
2. Choose language settings and click Next
3. Use Repair
If you dont own this disk contact with the administrtor.
File: \ubuntu\winboot\wubildr.mbr
State: 0xc000007b
Information: Could not load application or Operating System because of the lack of the required file or errors in this file

Please help me... I have very important data in Ubuntu 10.04 that I don't want to lose.

Can you boot your partition install (12.04)? If so, you can boot the Wubi (10.04) install from that one's grub menu. Also, boot Ubuntu and pastebin the result of the bootinfoscript – bcbc May 25 '13 at 21:17
@bcbc yes among three ( ubuntu 12.04 , ubuntu 10.04 and window 7 ) i can use two window 7 and ubuntu 12.04 but not 10.04.... but i want to go 10.04..... – nirajan paudel May 26 '13 at 2:25

Boot your 12.04 Ubuntu install and edit the file /etc/grub.d/40_custom using elevated privileges e.g. sudo nano /etc/grub.d/40_custom (or whatever editor you prefer)

Make it look like this:

exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry 'Ubuntu 10.04' {
        insmod part_msdos
        insmod ntfs
        search -s -f -n /ubuntu/disks/root.disk
        probe --set=diskuuid -u $root
        loopback loop0 /ubuntu/disks/root.disk
        set root=(loop0)
        linux /vmlinuz root=UUID=$diskuuid loop=/ubuntu/disks/root.disk ro quiet splash
        initrd /initrd.img

Then regenerate your Grub menu (grub.cfg) by running sudo update grub. After that you should see the 10.04 install at the bottom of the Grub menu every time you boot.

nice but i was hurried so removed the 10.04 from window 7. now i have only two OS window7 and ubuntu 12.04. i am sad that i lost my data specially software installed by my prof. i will have to visit him once again... whatever now i want re install the older version of ubuntu 10.04 but the wubi encountered another problem uffffffffffff.... an error ocurred can not download the metalink and therefore the ISO. now what can i do... i am being like a joker plz help – nirajan paudel May 26 '13 at 9:21
10.04 is already out of support, so Wubi won't work. Yeah there is a trick you could use, but I have to ask what would be the point in installing an out of support OS for some data that you already deleted. – bcbc May 26 '13 at 16:36
