"Windows must be installed on a partition formatted as NTFS"

Hello,

A few weeks ago I wanted to install Ubuntu 13.10 on my laptop, which is what I did using a bootable USB drive. Unfortunately, I deleted Windows 7 at the same time... I can't do without this operating system given the programs I need to use for my courses.
So I wanted to go back to Windows, but I don't have a CD. I downloaded the trial version of Windows 8 (.iso) and I made a bootable USB drive with it.
During the installation of Windows 8, I receive this message when I have to choose on which partition to install Windows: "Windows cannot be installed in this disk space. Windows must be installed on a partition formatted as NTFS."

I then tried to use Gparted, but unfortunately when I want to unmount my partition it gives me an error message:

"Unable to unmount /dev/sda1."

The partition could not be unmounted from the following mount points:

/

It is likely that other partitions are mounted on these mount points. It is advised to unmount them manually.

So here I am a bit lost... What can I do to install Windows on my computer?

Thank you in advance for your responses... :)

PS: It is not necessary for me to keep Ubuntu for the moment.

Configuration: Linux / Chrome 32.0.1700.107

Hi,

During the installation of Windows 8, I receive this message when I need to choose on which partition to install Windows: "Windows cannot be installed on this disk space. Windows must be installed on a partition formatted as NTFS."

Just before this message, for the partition selection, you should have a button (or link, I can't remember) marked "Advanced options" that you need to select, and then you will be able to delete the partitions and choose to install your system in the empty space.

Thank you for your response.

I have two partitions:
Drive 0, partition 1 (total size: 461.8 Go free space: 0.0 Mo type: system)
Drive 0, partition 2 (total size: 4.0 Go free space: 0.0 Mo type: logical)

I have tabs such as "refresh", "delete", and "load a driver" that I can click on.
And then I have tabs like "format", "new", and "extend" that I cannot click on...

What should I do?
