Cannot delete partition

Hello. I have a disk with 3 partitions:
1 - Windows 7
2 - DATA
3 - Linux Ubuntu

Recently I decided to delete Ubuntu once and for all. To do this, I followed this tutorial:
Partition or Volume - Delete

However I cannot pass step5. Once I click "yes" I get the most retarded and frustrating error message I've ever seen in all my life (and I've seen lots of them):
-"An unexpected error has occurred. Check the System Event Log for more information on the error. Close Disk Management console, then restart Disk Management or restart the computer."

I closed an opened the program - it didn't work.
I restarted the computer - it didn't work.
I checked the Event Log - Lot's of random information and garbage over all.

In order to fix the problem I spent the rest of the night searching for a solution, but my best friend Google has failed me, apparently no one has ever had this error before.... people usually get error codes or something similar to identify the errors ... but not me ... I guess I must be special ...

I've also decided to use diskpart and my good old friend - the command line. This is what I got:

DISKPART> list volume

Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 E DVD-ROM 0 B No Media
Volume 1 G DVD-ROM 0 B No Media
Volume 2 System Rese NTFS Partition 100 MB Healthy System
Volume 3 C NTFS Partition 147 GB Healthy Boot
Volume 4 D NTFS Partition 70 GB Healthy


Apparently, I want to delete a partition that Diskpart does NOT even recognize?? Why is this happening? Is it because the partition I want to eradicate is not in NTFS?
Do I need a 3rd-party program to delete it?

What do I need to do to fix this? Format the entire disk? (I am starting to consider that) ...

Thanks in advance.

I gotta say it... why doesn't everyone just download Partition Wizard Home Edition v5.2, install it under Win7, and use it... for everything hard drive and partition related?

Also, download and burn the ISO for Paritition Wizard's standalone boot CD, for those few special functions that must be completed outside of the booted OS (e.g. to manipulate the C partition in some significant way).

How many of these requests for help are tied directly to trying to use DISKMGMT or DISKPART to manipulate partitions, drive letters, etc.??? Every one of them it seems to me could be so much more simply, intuitively, and easily completed using Partition Wizard in the first place, and just never using DISKMGMT or DISKPART at all.

Yes... some/many/most basic operations can be accomplished with DISKMGMT or DISKPART, but not the total set of things that can be done with Partition Wizard. And certainly not with the ease and simplicity of Partition Wizard's equivalent functions.

Third party tools have extra fuctions usually.

However, Veritas were very careful with diskmgmt gui - almost impossible to mess up.

It also aligns to nt6 rules, and creates the correct disk and boot code.

The only 3rd party app. to also do that is Paragon ( new version 11 only )

Thanks for the help guys. I managed to figure out a solution for my problem using the OS install disk. Thanks for the help

Problem solved.

PS: is there a way to reward people with reputation points or something? xD

I agree entirely.

It's an excellent tool that I use regularly when fixing problems for friends and neighbours. It's free as well although it never hurts to make a donation if you're so inclined.
