Disassembling with IDA

Hi guys, I am struggling a bit with trying to get IDA to read BO3. I realise that the executable is packed so I have tried to dump it with task manager and read the dump but I still don't find any strings. Any information as to how I could maybe disassemble it would be appreciated

i tryed to learn the same and no one here wanna help you, you only get insults and jokes so dont lose time here.
