The BIOS that I downloaded a month or 2 ago does not fix the problem.
The problem appears to be that if the BIOS detects the factory hard drive in the HDD bay, it will attempt to do a "turboboot." I'm not sure what that means, but that is what another poster said a few posts back.
In any case, the system gets confused on boot and what you get is a continous loop of the Lenovo splash screen, which can be interupted with an F12 boot config menu. The other option (that I do not use) is to use the recovery boot button.
Apparently you can get around all of that by swapping the factory drive to the caddy (and presumably booting from the new drive in the HDD bay).

thanks for the reply.
Does anyone uses Linux as OS in a caddy-configuration? If the fastboot is the failture, it could be that Linux would work out of the box, because the bios loads there the bootloader shim (signed) and afterwards grub2 is loaded by shim. Then the bootmenu is shown and from there you can choose the bootmanager from windows or load the Linux-kernel.
Does anyone has a Linux-configuration like this double-boot-config?

I believe this issue occurs due to hardware limitations of the Caddy (inability to handle SSHD drives, or inability to handle SSHD's capacity of 1TB + 8GB - most Caddys handle up to 1.000GB).
However, can somebody please try to disable Fast Startup in Windows 8 and see if the device will boot with the two drives in place?

there are other Forums, which discuss the failture. If they are right, then you have to disconnect the hybrid-drive, exchange internal to ssd and caddy mounted with hdd. If the hybride-drive is connected to the z710 it falls into bootloop.
Does anybody knows, if a other hybrid-drive (different brand) is working in such a setup?

is there anything new about this problem?
I tried HDD caddy with 320gb HDD and there was no startup loop.
When I try with 1TB hybrid drive or 1TB ordinary drive, there is startup loop in both cases.

The solution is quite simple. The problem is the original hdd in the Lenovo Laptop. With the SSD in the caddy just start up the system trough the recovery key and use the boot menu with the windows boot option. After the boot copy (read: cloon) the original HDD to the SDD. Replace the original HDD with the cloon SSD and then throw away the original HDD.
Because with the original HDD in the system the boot problem will contain. Buy a new hard disk for use in the caddy.
System should work than perfect.

I have the same thing, I have the z710-01099 with samsung 850 EVO now in place of the original HDD and the original HDD in the caddy. This results in a boot loop which only can be broken by booting with the OneKey Recovery key or a bootloader. I really hope lenovo comes with a solution to this problem.

Well, I'm joining the club.
This is really unbelievable. I spent 850 € on this laptop and all I have is problems. First the subpar display with horrible viewing angles and impossible to get any decent color calibration and now this.
Can anybody confirm that it works normally with any other HDD in the caddy?
