[SOLVED] Problem boot Mageia on USB

Hello, I'm a new in the Community and i really want to install Mageia 2.
I've got an ASUS U36S and so there isn't a CD PLAYER.
I have downloaded "Mageia-2-LiveCD-GNOME-Europe1-Americas-x86_64-CD" And Lili.
When i try to boot on USB I have a black screen with "grub >" and some command... I tried "boot" but nothing. I tried "find /boot/......" but "file not exist".
So i try to mount Iso on usb with Unebootin, rufus or fedroaUSB And now with these softs ,if i want to see my USB in my BIOS, i have to Enable "UEFI Boot" but when i try to boot, my Computer boot on win7 ..
My question is simple, how i can install Mageai ??
Thank you very much and sorry for my English ...!
