I assume you've verified that the SSD has a GPT partition table. It's
unlikely that it isn't, but just make sure. The problem is more likely
that you are booting from the secondary drive. I think there's a small
button somewhere to set the boot options. Check in the disk selection
and partitioning screens.
I found it and verified that it works. On the hard drive selection
screen, in the bottom left corner, there's a boot selection link. Click
that and you will get a dialog box that will let you select the other
hard drive as the boot drive. Then it won't complain about the EFI
partition.
