Fedora 19 (you have not created a bootloader stage 1 target device)

Good day. I want to install fedora 19 on my hdd but i get this errors :
you have not created a bootloader stage 1 target device sda6 must have one
of the following disklabel types: gpt.
I tried:
1)Create 1-2 mb bios boot particion. (does not work) 2)Change UEFI to
Legaci first in bios (usb does not boot) 3)Delete BOOTX64.efi in EFI
folder in bootable usb (usb does not boot) 4)Use other usb creator -
unebootin,lili usb, linux live usb creator (does not work)
Where is problem? I have got lenovo z500. Sorry for my english. I'm not
from English speeking country.
