open disk utility and format the new sata drive in HFS+ (GUID), click in "restore" (disk utility), put (drag&drop) the first drive (ata) into the "source" and put the second drive (sata) into the "target" apply.

When the "restore" finishes, take note of the device id (SATA drive "diskXsY")download and extract the efi pack into your desktop (ata drive) open a terminal and type

sudo -s
(password)

cd /Users/"your user"/Desktop/pc_efi_v80

diskutil unmount diskX (Sata drive)

./startupfiletool /dev/rdiskXsY ./boot_v8

dd if=./guid/boot1h of=/dev/rdiskXsY bs=512 count=1

dd if=./guid/boot0 of=/dev/diskX bs=400 count=1
(if you get "resource busy" open diskutlity and unmount the disk)

X=Sata drive
Y=leo partition

that´s all ( change in bios the default boot hd or use the bios boot selector)
