I've enjoyed using Ubuntu 13.04 but I'd like to install Windows 7 over Ubuntu so I have a fresh install of Windows 7 thats use all of my HDD, I'm not new to Ubuntu I've been using it for a few months but I can't seem to find this and I've tried unetbootin and gparted and other applications but it never seemed to workout, anyways I have Windows 7 on an iso and I'd like to put it on an USB and install from there but apparently it's not as simple as it seems.

Installing Windows over Ubuntu is pretty easy, as Windows takes up the whole disk by default.
- First, boot to the CD (you may need to modify your boot order in BIOS to acheive this)
- Now, choose your language
- Click 'Startup Repair'
- Go into Command Prompt
Type format c:(this is required because Windows does not understand Ubuntu's filesystem, so it needs to format it)- You should get a warning. Just press Y.
- Wait for it to finish, then install Windows
- Profit!
Boot from the Ubuntu live USB or DVD that you used to install Ubuntu and reformat the entire disk to ntfs format using the built-in GParted partition editor app from an Ubuntu live session. Then boot the Windows installation media and install Windows on the new ntfs partition that you just created.
Boot the Windows installation media by powering up PC while pressing the PC's one-time BIOS boot menu key. If you see a UEFI version of the bootable flash stick or DVD then choose that, as you have the modern UEFI BIOS which is more secure and stable and offers mouse support.
An example of the difference is shown here:
Each boot menu is slightly different. Above shows Windows Boot Manager which should appear as first boot device after a UEFI install.
A UEFI install requires booting the installation media as a UEFI device, deleting all partitions to clear formatting. You may need to turn off Fast Boot in UEFI Firmware to boot UEFI installation media from the BIOS Boot menu. A UEFI install should configure Windows Boot Manager as permanent first device in the Boot priority.
