Replacing DVD drive with HDD?

Question

Hard disks

Notebook Lenovo ideapad z710 instead of a DVD drive installed a DEXP AT-DH01 adapter. The BIOS sees both disks, in the settings the priority is on the old disk, but os is not loaded.
If you pull out a new hdd, wait until os boots up and only then insert the adapter with the disk, then the device manager will not see it.
The adapter is correct. If you insert an old hdd into it and boot the system only with it, then everything will work.
What can be done in this situation?
The adapter has a switch with three positions, in all positions the situation is the same
. UPD:
The standard one has a native hdd with an operating system. Extra in adapter.
I formatted an additional hdd, the system saw it and works with it. But loading os is crooked.
If you just press the power button, then the download does not go beyond the Lenovo logo, it does not give any error, but the screen just flashes and shows the logo again. To enter the system, you need to press the recovery key, then a window appears asking you to enter the BIOS, continue normal boot, or choose what to boot yourself. So to enter the system you need to manually select the desired OS.
Only two OS on the main hdd.

Answer 3

From the category of "considerations":

1. Lenovo loves to sell extras. components for your hardware yourself. Try to make sure that there are no restrictions of such a plan (only native sleds are needed).
   
2. Check that there are no tricks and the laptop really sees two hard drives, and does not consider that it has a hard drive and an optical one. drive unit.
   
3. EMNIP, the switch must be set to the middle position of the three.
   
4. Is there really enough food?
   

Answer 4

The adapter is correct. If you insert an old hdd into it and boot the system only with it, then everything will work.

There was the same problem on the old acer, I put the hard drive with the OS into the adapter, additional to its native place. works to this day.
