Problems with my ACEPC AK2

[Mo06]

I have an ACE PC.

Model: AK2 RAM 8GB ROM:128 GB
Serial No: A2E0BT843961

My problem: Windows 10 froze and I had to reboot the machine, I now just get the following message on start up:

'Reboot and select proper boot device
or insert boot media in selected boot device and press a key'

This happened a couple of months ago, I got no response from ACEPC support, so I did a temporary fix by booting up from a Linux (Mint) USB drive.
I've been running it like this for a few months, works but not ideal (it sometimes freezes, I have to reboot and of course lose all logon IDs).

Anyway, I suspected the internal SSD is faulty, so I bought a new Kingston 120 GB SSD.
I installed the new drive in the space under the lid, but what I cannot figure out is how to change the boot priority so that I can boot from this new working drive.

2. You can change the boot in the BIOS interface,
Steps: Turn on the computer and press Delete to enter the BIOS, change the boot sequence under the BOOT option.

Thanks, but the links don't work.

Is the system file link unable to download?

Yes, the video works but I cannot download the files.

EDIT - I have downloaded the files and will see if I can restore the sysem.
