"No valid boot loader target device found. See below for details.
For a UEFI installation, you must include an EFI System Partition on a
GPT-formatted disk, mounted at /boot/efi."
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.
