How to repair Mbr for my ubuntu on local drive D

edited August 2012 in Ubuntu
I installed ubuntu with wubi installer on my local drive D. Few months ago, I reinstalled my windows and the mbr of ubuntu has gone. So I tried to repair it by booting from live CD and installing boot repair. However, as I installed not on drive C, but on drive D, the boot repair didn't work.
I tried to uninstall the wubi but couldn't. Windows said it didn't installed correctly.
Any ubuntu geek can help please?

    Did you try this?

    Note that the 'identifire from Real-mode Boot Sector section' with the command "C:\Windows\system32>bcdedit".
    Be sure that the description should be Ubuntu.

    To change the drive or partition, enter the following, substituting {device_id} for the identifier of your drive from the identifier listed under Real-Mode Boot Sector, and X: for your Drive letter designator.

    C:\Windows\system32>bcdedit /set {device_id} partition=X:

    you need to add the path to our Ubuntu install. The path should be \ubuntu\winboot\wuildr.mbr, though this may be different, depending on your setup. Browse to your Ubuntu folder to check if you’re not sure, and then enter the following in the Command Prompt, substituting \your_ubuntu_path for the correct path to the Ubuntu files in your computer.

    e.g. C:\Windows\system32>bcedit /set {device_id} path \your_ubuntu_path\winboot\wubildr.mbr

    **** Please do it at your own risk.****

    How do you uninstall wubi after Windows reinstallation?

    because I installed wubi in my drive D and my original windows was in drive C. The wubi files were left in drive D.

    ဟုတ်တယ်လေ။ ဒါပေမဲ့ ဝင်းဒိုးတင်လိုက်ပြီးဆို Uninstall programs မှာမပေါ်တော့ဘူးလေ။ အဲဒါဘယ်လို uninstall လုပ်ပြီး Windows က didn't install correctly လို့ ပြောတာတုန်း။

    I usually clone Ubuntu on PCs of the same type just by copying root.disk file.
    (Find it in D: drive)
    If I were you, I would not repair the boot loader.
    I will just install a new one.
    Before the restart and installation, replace the root.disk.
    Then restart.

    I did according to the above link's method. When I restart my computer and choose Ubuntu boot entry I added, the system said the application could not be loaded. It may be missing or corrupted.
    Seems the only way left is to delete manually and reinstall again.

    How about grub-install from live cd or linux rescure ?

    - first boot from some same karnel linux like live cd or linux rescure.
    - if you mounting your system /dev/hda at /mnt grub-install is as below.
    # grub-install --root-directory=/mnt /dev/hda

    And then try agrain from your ubuntu dual boot management screen.

    Thanks ko ATT. But I have deleted the folder.
    I tried to reinstall the latest ubuntu 12.04 but when I reboot and the system preparing to run
    for first time, it freezes. I looked up in the forums and many others had faced that problem too.
    Now I decided not to use ubuntu meanwhile as it is so troublesome.

    Sorry for late response.

    - ubuntu OS is not bad, but I usually use CentOS (vps, loadbalancer, database, web, everything)
    - Did you install from usb (like netinstall from usb) ?
    - Let me know the messages before freeze or let me see your freeze screenshot.
