Old HDD compatibility issue

[Infestation]

Hi guys, I just finished my first build, and everything is working far better than expected! I installed windows on a new SSD, but when I plug in my old HDD, that has a version of windows installed on it, the computer fails to boot, with no power to usb ports (cant force enter into bios).  When I unplug the HDD, the computer boots fine. My goal is to ultimately retrieve a couple of documents from the HDD and then wipe it. Any help in doing this would be greatly appreciated.

 

Details:

OS: windows 10

Motherboard: Asrock x370 killer

HDD: some old generic no name brand.

 

Do you need any other details?

Remove Windows from the old HDD.

Well obviously thats the goal, but as a newbie, I am not sure how to do that without plugging it into a working computer, and when I try to, it fails to boot. My old PC mobo died tragically.

Change Driver order in UEFI/BIOS, and check if SSD is still in boot menu.

Not sure if this would work, or if its safe, but you may be able to power on the system and boot from the SSD, and then plug in the HDD and work from there. 

Does anyone else know?

USB to SATA adapter, enclosure or dock.

Electrically speaking, both SATA data and power cables put their ground pins out farther so that when you connect them, ground connects first, this makes them safe to hot swap.  However not all SATA controllers support hot swapping of drives but if they don't support it, it'll be 'safe' it just also 'won't work'.

Hot swapping worked, thank you for the suggestions!
