Hi CentOS Team,
                             i am not able to install CentOS 6.0 , while installing

1) Insert your CentOS 6.0 installation DVD into DVD drive
2) In the pre-boot phase of system startup press <F11> to enter UEFI Boot Manager
3) Enter 'UEFI Boot Settings'
4) Choose 'Add Boot Option'
5) Point to 'BOOTX64.efi' file, whose exact path is /EFI/EFI/BOOT/BOOTX64.efi on the DVD
6) Add Description (e.g. "CentOS 6.0") and optionally add Optional Data (which is passed to the boot image, not necessary)

when i press the F11 i am not able go to boot options , for that i used the del and esc,
there i am not able to find the UEFI settings,
i tried with enabling the ide configuration to raid and enabling the sata0 and sata1
still i am not able to install CentOs .
please guide me to install the centos
