This question already has an answer here:

So I have an old windows vista laptop on which I decided to try ubuntu.

I thought I had got it right, but the windows OS is still there. I know it works alright as it is, but I'd like a fresh start with my pc, without the windows part. There is only one HDD in this computer, with both Ubuntu and windows. i noticed that after I installed Ubuntu, my HDD seemed to have split into two partitions (is this of any point?)

I wonder if I just format the HDD will i loose my Ubuntu installation? will it not be able to complete? will it not format the partitions?

Should I just format the entire pc using a bootable usb-stick and then install Ubuntu likewise? if that's the case, is there an ISO file somewhere that will do both or will i have to do this in two separated actions? like ... first making a bootable usb for formatting, and then making an other one to install Ubuntu (again)?

i have to problem to lose everything that's on the hdd whatsoever. I just need a fresh hdd with ubuntu, and the easiest way to do it?

If you want to simply remove Windows completely and then resize your current Ubuntu installation so that it uses the entire hard disk, then this answer by To Do will tell you how to do it step-by-step. – karel Aug 20 '13 at 14:32

If you want to fresh install Ubuntu and totally wipe out windows then all you have to do is create a bootable Ubuntu Cd or USB. Restart your computer and boot from the USB or CD(Depends on what you created) choose try Ubuntu live version. When you are booted in Ubuntu click install and now you can choose between installing alongside windows or format HDD and install Ubuntu, so choose the second one and you are Done.

You can also use Gparted to delete your windows partition(If you have installed Ubuntu in its own partition) and you will be left with ubuntu Hope i have helped.

So, you want a new installation with just Ubuntu on the computer? That is easily accomplished! The easiest way to do that, is to re-run the installation program and choose the "Erase disk and install Ubuntu" option.

It is likely that you proceeded with just the default settings on your install. Don't worry, that's fine! However, the default setting is for Ubuntu to install alongside an existing installation.

You will want to create a bootable USB. Luckily, you'll only need one usb. Follow the instructions here:

So if I understood correctly, you currently have a working dual boot Windows/Ubuntu, and you want to get rid of your Windows partition.

First, I encourage you to reconsider this decision; I find it's always nice to have more than one system installed on a computer (Mac/Windows), and as long as you don't actually need the space occupied by the Windows partition, you have nothing to loose keeping it.

Now, if you really want to delete it, I don't exactly agree with Colyn on the point that his/her solution is the simplest, and you will definitely loose your current data if you do that. Gparted is a software able to manage the partitions on your HDD. This includes the ability to remove/format partitions.

Go ahead and start GParted from the launcher. There you should see your Windows partition (formated in NTFS normally). Right-click on it, and chose "Delete". Then format it in ext3/4 depending on the filesystem you chose for your installation. Finally, click "Apply" on the top-left corner. You just deleted your Windows partition.

After this step, DO NOT forget to run the following command to upgrade your boot table before any reboot: sudo update-grub.

If you want to merge this new partition with your current one, it's another story. If you want to, ask a new question and include the results of the commands sudo blkid and sudo fdisk -l (Note: please be very careful to write the last command correctly before pressing Enter, fdisk is a dangerous utility).
