I am trying to install/live run Ubuntu 12.04.4 on Sony Vaio TGZ laptop. I've downloaded the ISO from the Ubntu website. Formatted a 16gbit USB drive as 32bit FAT. I've downloaded the UUI and run it to install the OS on the USB drive. I run the WUBI.exe which gives me 3 options: reboot now, reboot later and help with boot from CD. Click on any of these and then click finish and then nothing. I have set the laptop to boot from USB first. Help, please.
