This has been discussed many times I assume. Windows 8 uses a bootloader different than Windows 7 / Vista uses. Windows significantly changing its boot system settings & options. Therefore, its pretty much unclear how wubi would respond to it. Even in Ubuntu's official website under Install Ubuntu with the Windows installer explains;

Windows installer is not compatible with Windows 8 or UEFI firmware, and is not available for Ubuntu 13.10.

Ubuntu also making a statement here as below;

With Wubi, our officially supported Ubuntu installer for Windows, you can install and uninstall Ubuntu easily and safely. For 12.04 LTS only.

I would recommend you to install it on a separate partition for Ubuntu on its own. In such case, you may refer Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported)

Also refer Can I install Ubuntu inside Windows? to see more information
