How to recover Ubuntu installed with Wubi with corrupted GRUB

Question

I have ubuntu installed inside Windows 7 using Wubi.

Yesterday, I tried installing Ubuntu using GRUB but it seem that GRUB was corrupted. To recover, I fixed the MBR using the Windows 7 CD.

Now Windows 7 is booting from GRUB menu, but when I select Ubuntu the system reboots.

How can I fix the problem of booting into Ubuntu? I can see the Ubuntu installed in the Windows 7?

If you have found an answer suitable of accepting, please do so immediately. — Mochan, Dec 26 '12 at 11:38

Cant you use the recover function of Windows to go back in time? If I remember correctly, it's under System Tools.

That doesn't sound like a good idea - it (hopefully) won't mess with the hard drive's boot sector. – loevborg Jun 17 '11 at 13:21

One way would be to use EasyBCD, a free tool which is like Grub editor for the Windows Boot Manager.

The steps involved would be :

Install EasyBCD
Add an entry for Ubuntu (Wubi) using EasyBCD
Open a command prompt Win+R -> cmd and then type bcdedit
Note the entry (device-id) for Ubuntu that you just made
Run bcdedit /set {device_id} partition=X: (This is if your Ubuntu wubi was installed somewhere other than C:\)
Run bcedit /set {device_id} path \your_ubuntu_path\winboot\wubildr.mbr and substitute the correct path to wubuildr.mbr on your system
