Hi, I'm using Ubuntu 14.04.1 and tried using UNetbootin and the method before that, on the TinyCore non-CD installation Wiki. When the GRUB menu pops up, I only see Ubuntu, an option to open the BIOS settings and another one that isn't the USB. It may be due to UEFI. Is there a way to wipe my whole drive so that the USB iso boots? Thanks in advance.
