Install to mini pc

hi all
trying yo install os to my acer revo rl80.
followed all steps but when i boot up after all the lines end up with a large “home assistant” zx spectrum style with “welcome to home assistant command page” and a bunch of network info underneath.
as you can tell im not a computer programmer.
what am i doing wrong.
many thanks
ben
sorry if im being a muppet here.
thanks
thanks again
sorry

There is no interface on the OS install. You use the network info to login from another PC/Laptop/device to the actual interface

am i supposed to add this? i cant find anything searching.
i flash installed to new drive using a usb/sata cable…did that not include interface?
again… thanx

I meant u use a browser to login into HA with the info provided
