When using UNetbootin I am unable to locate the Vista usb drive displayed ( CD J:,F:,G:,H:,J:, ((K:<which is what the usb is showing) my UNetbootin is showing drives F:\, G:\, H:\, I:\. Is there a way to make Vista switch the letter for the usb, let's say from K: to F:,G:,H:,I: ? Also I have formatted the E: drive but only exFat is available not Fat32. Also I want to mount Lubuntu 13 directly to drive E: the exFat format - I am trying LiLi usb creator, UNetbootin and most sites suggest using a DVD or usb to mount to an external hdd with Vista. What happens next, must I buy DVD-Rs?
