If you installed Ubuntu with a CD or USB Live version you can boot to that, open GParted and choose the partitions you wish to delete(depending on your install it may be one partition or several-root,home,SwAP could be separate or one) and then right click those partitions and choose delete. This is not a secure delete though, for that you would need to burn a copy of Darik Boot and Nuke (http://www.dban.org/) and boot to that and securely delete Ubuntu partitions.

Beware if you have a Dual boot with Windows above direction will lead to problems only follow if Ubuntu is only OS on system

i dont get it, why it's not secure... And is there any better guide step by step for some secure complete uninstall?

Can you explain me what i have to do?

ubuntu is my only os on system

By secure delete, I mean that it is possible that files could be recovered by someone later. Thne way to avoid this is through overwriting the files you delete. That is why I suggested Darik Boot and Nuke
I would recommend it if you have any sensitive information on your hard drive such as financial records
