When loading Ubuntu cd,options drop-down install inside windows is chosen,an error message appears re wubi.2 I cannot uninstall version I bought some time ago that lays dorment in c drive,why?

Boot the Ubuntu cd. One of the items on the drop-down menu should be something like "Boot from CD". Choose that option and boot the CD. All the files on the CD are compressed and must be de-compressed before applications will run, therefore it will run slower than applications which are installed on a drive.

Once the CD is booted, open a console and run this command: sudo fdisk -l (that's fdisk dash ell and not fdisk dash one).

Show the output of fdisk here so that we may see the organization of the partitions on your hard drive. With that information, we may be able to tell you how to remove Ubuntu.

@bigrigdriver

This isn't a traditional install, it is wubi, it is actually installed on the windows partition

that's about all I know..
and don't have windows available to test/learn
Edit;
Background info
https://wiki.ubuntu.com/WubiGuide

From the Wubi install manual:
In the Windows menu, near the bottom, is something like Run or Run command. Click on that and enter C:\ubuntu\Uninstall-Ubuntu.exe

Does that work?

My understanding was that ubuntu no longer supported using wubi.

No idea..

But my thinking is..

If it created a mess.. they should clean it up

I guess I can try to emulate the problem, I have a vista license for my laptop
yes it is that old.. but younger than my desktop and both 'run' debian testing (currently Jessie ) very well

Lets wait for info

Thankyou kindly for your support,my ineptitude in articulating problems is directly proportional to my esoteric visissitude."pig ignorant". Issue 1. when I enter add and remove programmes and press "unistall" response; it gets to a point,then, a window appears cannot find a particular file, seems it lives in the Wubi programme that was layed down upon the installation Ubuntu version 12 blah blah.therefore cannot remove programme.

I bought Ubuntu 12.04 the cd has a 2.38mb application called "wubi" before the install can take place, it must first remove earlier version. It begins that task,but,alas,it spits out cannot remove software file missing and a reference to wubi.

perhaps this will help

How do I manually uninstall Wubi?

Remove C:\ubuntu and C:\wubildr*

In Windows XP you need to edit C:\boot.ini and delete the Ubuntu/Wubi line. Alternatively you can modify the boot menu via Control Panel > System > Advanced > Startup and Recovery and pressing "Edit". For Windows 98 you have to edit C:\config.sys and remove the Wubi block. For Windows Vista/7, you can use the built-in bcdedit command or install EasyBCD to edit the boot menu. To use bcdedit, run cmd.exe as an administrator, then enter bcdedit to show all boot entries, note the {GUID} specified for the Ubuntu entry, and then remove it: bcdedit /delete {GUID}

To remove Wubi from the add/remove list, delete the registry key: HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Wubi

An easy method of removing this registry key is to paste the following text into a plain editor such as Notepad, close and save the file as something like removeWubiKey.reg (you may wish to go to Folder Options > View and disable the "Hide file extensions for known file types" option to check that the .reg extension has been applied correctly). Then you can perform the rest automatically by opening the file in the normal Windows manner, or choosing the "Merge" option from the right click context menu. Note: The formatting is rather strict, so copy the text exactly for best results. You may need to be logged in as the administrator to delete the key, depending on the version of Windows you are using. User Account Control in Vista may also ask for permission, in the typical fashion.

REGEDIT4

[-HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Wubi]

After deleting the registry key, Ubuntu may still appear in the program list. If this is the case, you may be asked if you would like to remove the item from the list.

You remove Wubi using Windows Control Panel-->Remove Programs (or whatever they're calling it these days), just like any other program installed in Windows.
