I just got a desktop PC from my friend that runs a dual boot of Windows Vista and Ubuntu.
He has two hard drives in the computer, C: for windows and D: for Ubuntu.
This is what the disk management looks like:

So, can I still use the EasyBCD Vista bootloader reinstall method and then just delete that D: partition?
The files for D: are still accessible and usable on the Windows boot.

I think Ubuntu is installed with WUBI. You can remove it using 'add/remove software' from Vista, just as you remove any windows program.

It's not, I already checked.

Can you boot into Ubuntu? If yes, then post the output of:


sudo fdisk -l

from ubuntu and also post a screeshot from GPARTED of your partitions.

Please post the output of the command


cat /etc/mtab

It is faster are uses less resources to cut and paste from the terminal window to this editing window instead of attaching screendumps.

In order to make it easy to read, please high-light the text and click on the # icon above this window to mark it with code tags.

from the bootloader path of ubuntu it sounds like it's installed with WUBI, but I don't see it at all when I go to the uninstall program list

cat /etc/mtab would show it.

There is no Ubuntu on those disks. Both Disks are formatted with NTFS and Ubuntu/LInux does not install on NTFS partitions or drives. It is either WUBI or you don' t have Ubuntu.

Actually, I found the /ubuntu folder in the D: drive.

There's an 'uninstall wubi' executable file. Running this will totally uninstall it?

^ This is the way to remove a wubi installation. ^

If I try to run the uninstall-wubi file, I get this:
http://i39.tinypic.com/ajuo9l.jpg
Which is apparently an error code for when you try to run something with the wrong drive letter, so you have to go into disk management and change it.

But I was looking at the Wubi Guide at https://wiki.ubuntu.com/WubiGuide
and under the manual uninstall guide, I can either use EasyBCD or go into command prompt and run bcdedit and then type bcdedit /delete {GUID} to remove it.
So it's essentially doing what EasyBCD does, I guess.

Does this fully uninstall it? I don't want to mess the bootloader or computer up.

So, to my understading, what WUBI does it create a option in the boot menu to boot to Ubuntu.
Using EasyBCD or the bcdedit command removes this option from the menu, only leaving Windows, therefore it boots automatically to Windows.

Ubuntu is only existing as a file within the D: drive which I can just delete,
thus removing Ubuntu entire from the system.

I think you as much as I do about the wubi installation now :-)

So if you remove

1. the option from the Windows boot menu, and

2. the big file which contains a file system, which holds the Ubuntu installation,

there is not much left (probably nothing that will cause any trouble or occupy any significant disk space).

Do you want a regular installation of some other flavour of Ubuntu or some other linux distro? For example, if your computer is getting old, the standard flavour of Ubuntu might be slow, but it may work very well with a lighter desktop environment.

Or do you want to continue with only Windows?
