HAOS installation on Generic x86-64

I can’t install HAOS on Generic x86-64.
(Lenovo ThinkCentre M900, 16 Gb RAM, Kingston 500 Gb SSD)
With method 1 in the end the disk does not write “authentication required to open Kingston”, end of the movie. I have also tried with root user.
With method 2 it only opens CLA and I don’t know how to go to homeassistant.local:8123 because there is only a command line, not a browser.
Maybe I have read little?
Is there any document that explains it?
Can somebody help me?

There is only a command line, HA is a headless server, so no browser. You need to manage HA from another device using a browser

Thanks, I had thought that HAOS would have some option to manage locally. From another networked machine, I can see the graphical interface and manage HAOS
Thanks, again.
