Ubuntu – How to remove the extra Ubuntu option on the Windows Boot Manager menu

wubi

I installed ubuntu using Wubi side by side with Windows. I decided to uninstall ubuntu and install Kubuntu, which I did successfully. However now when I boot my computer, the Windows Boot Manager displays 3 options:

  • Windows
  • Ubuntu
  • Kubuntu

The Ubuntu option does not work, but the entry did not get removed when I uninstalled Ubuntu the first time. How do i get rid of this extra entry?

  • For Windows Vista, 7 or 8, run bcdedit as an administrator (hit Windows key, type cmd, look above and right-click CMD.EXE and select Run as administrator).

    This will list the Windows Boot Manager entries:

    C:\Windows\system32>bcdedit
    
    Windows Boot Manager
    --------------------
    identifier              {bootmgr}
    device                  partition=\Device\HarddiskVolume2
    description             Windows Boot Manager
    locale                  en-US
    inherit                 {globalsettings}
    default                 {current}
    resumeobject            {1476af5e-e5bc-11de-b180-0024543ae029}
    displayorder            {current}
                            {1476af63-e5bc-11de-b180-0024543ae029}
    toolsdisplayorder       {memdiag}
    timeout                 10
    
    Windows Boot Loader
    -------------------
    identifier              {current}
    device                  partition=C:
    path                    \windows\system32\winload.exe
    description             Windows 7
    locale                  en-US
    inherit                 {bootloadersettings}
    recoverysequence        {1476af60-e5bc-11de-b180-0024543ae029}
    recoveryenabled         Yes
    osdevice                partition=C:
    systemroot              \windows
    resumeobject            {1476af5e-e5bc-11de-b180-0024543ae029}
    nx                      OptIn
    
    Real-mode Boot Sector
    ---------------------
    identifier              {1476af63-e5bc-11de-b180-0024543ae029}
    device                  partition=C:
    path                    \ubuntu\winboot\wubildr.mbr
    description             Ubuntu
    
    C:\windows\system32>
    

    Note the Real-mode Boot Sector entry that has a description of Ubuntu. Copy and paste the identifier and then delete it as follows (in my case):

    bcdedit /delete {1476af63-e5bc-11de-b180-0024543ae029}
    

    For Windows XP, you can edit C:\boot.ini. I recommend making a backup first as an error can prevent Windows from booting. Also you should edit it as follows:

    1. Right-click My Computer, and then click Properties.
    2. On the Advanced tab, click Settingsunder Startup and Recovery.
    3. Under System Startup click Edit.
    4. Delete the line C:\wubildr.mbr = "Ubuntu"
