I used the Universal USB Installer application to copy the latest ISO image from Linux Mint DE (64 bits) and install it on my PC, however when I try to reboot it I have the option to choose my connected USB device as "UEFI: ... USB ..." but when I choose it it doesn't do anything, the screen goes black for a couple seconds then loads windows 7 normally.
Should I do something before trying to boot into the USB device? This is my first time trying to install a linux distro on a UEFI-based PC I never had a problem like this before. Thanks in advance.

.efifile in the USB to be able to boot it? I was browsing the files and there's no EFI folder or anything like that – javiervd Dec 27 '12 at 0:45
