Windows 8.1 won't start from ssd when hdd is inserted. How to fix?

Question

Hard disks

An ssd was installed in place of hdd, winodws 8.1 was installed on it. When the hdd is not inserted instead of the dvd drive, the laptop boots up, but when I insert the hdd, the laptop apparently starts loading from the hdd but hangs on the boot animation. How can I set boot from ssd when hdd is inserted in laptop?

Answer 1

Hmm, you probably installed it with UEFI support
. I have a similar picture, I installed Windows with UEFI support, and on the second Ubuntu, it turns on normally separately, and as soon as two HDDs are connected, everything that can boot is Ubuntu
Reinstalled without UEFI support, the problems disappeared, but what was I did not understand.
But there is a feeling that this is due to UEFI

Answer 2

Yes no UEFI was not enabled.

Answer 3

Em. And in the BIOS from which device did you install it first of all?
