Isn't it easier to do this:

1. Pop in the Live CD, boot from it until you reach the desktop.
2. Open a terminal window or switch to a tty.
3. Type "grub"
4. Type "root (hd0,6)", or whatever your harddisk + boot partition numbers are (my /boot is at /dev/sda7, which translates to hd0,6 for grub).
5. Type "setup (hd0)", ot whatever your harddisk nr is.
6. Quit grub by typing "quit".
7. Reboot.

I may be missing your point though, if so, please forgive me :)

Restore GRUB quite simple in Ubuntu, instead going through all the "gain root access" and play with shell commands, you can use the Ubuntu installation CD to restore it without going through all kinds of hassles.

Here are the steps:

1. Boot your computer up with Ubunto CD
2. Go through all the process until you reech "[!!!] Disk Partition"
3. Select Manual Partition
4. Mount your appropriate linux partions

/
/boot
swap
.....

5. DO NOT FORMAT THEM.
6. Finish the manual partition
7. Say "Yes" when it asks you to save the changes
8. It will give you errors saying that "the system couldn't install ....." after that
9. Ignore them, keep select "continue" until you get back to the Ubuntu installation menu
10. Jump to "Install Grub ...."
11. Once it is finished, just restart your computer
i hope it will helpful to you.
Good luck!.

If you are using a program on a CD to restore the image it is likely that program is Linux based and the GrubforDOS loader applies to the CD you are trying to boot.

If you remove the CD do you still get the same message?

Just checking: you are trying to start Windows 7, right?

GrubforDos is a Linux installer. Do you have any Linux operating systems on that machine?

Have you installed any new programs on it recently?

Sorry didn't read all of your message no I was trying to back up and clear some space on my drive's at the first time I think a windows update was loaded at some stage that day

Try this: start the laptop and immediately start pressing the F8 key. This should bring up the Windows Advanced Start Menu. Then select "Start Windows Normally" and see if you can get in.
