vaio currently running ubuntu cant reinstall windows 8

Have you tried installing Windows by inserting your disc first, and rebooting your machine, setting your BIOS to boot off your optical drive? That way you should be able to run the Windows installer, otherwise there maybe runtime issues under Ubuntu.

All the best. :)
