You can't use Wubi with Windows 8. – Braiam Dec 15 '13 at 19:14

First, WUBI is useless on a computer that uses EFI to boot. Don't even bother trying to use it.

Beyond that, the Samsung "bricking" problem has been worked around by new kernel features. I don't know precisely when Ubuntu implemented these features, but I'd be shocked if they weren't available in the latest release (13.10). If you want to be absolutely sure, you can install and use Ubuntu in BIOS/CSM/legacy mode -- but this is awkward unless you also convert Windows to boot in the same way. The least awkward way to mix boot modes is to use my rEFInd boot manager: Install it in Windows, add hdbios to the scanfor options in refind.conf, and install Ubuntu in BIOS mode.
