Replacing ceiling light with recessed light

I am trying to change a ceiling light to a recessed light. The problem i am having is there is one metallic cable with two black wires, and two non metallic wires both with a white, black and copper. When i tested the wires, only one of the wires was hot, and it is white. Tested with light switch on and off.

not sure how to proceed, i unfortunately didn't take pictures of the original light. I have a picture of where i am now. Any ideas?

If you used a non contact tester your tests are meaningless. You need to test with a multimeter or test light.

What is the wiring at the switch.

Hi, looks like a blue conductor 2 blacks and a white are wire nutted together, that BX cable will have a white and black, is there anything else in the area not working? over time the white may be dark, do you have access above ?

Thanks for the replies. I am using a voltage meter to test the wires. I nutted the two blacks and a white together just so the wires weren't exposed. That's just a little blue painters tape on the wire, it's black though. Still need to check on the light switch wiring, had to take a break.

I'm very much a novice here, thought this would be straightforward but nothing ever is in a old house.

I labeled the cables for discussion purposes. The splices don't look correct from what we can see.
Can't tell if there are three or four cables there.

A - white and black and B - black connected ..... is not correct.

You'll need to open those splices. It looks like cable A is the feed cable and cable B is a switch loop.
Cable C is BX and would normally be the feed cable in an old house.
Not sure what I labeled as D is even a cable.
