Ok, I’m limited on time but I still decided to publish this walkthrough for installing SharePoint Server 2010 farm in one server…
Install software rerequisites
Install SharePoint Server
Server Farm
Configuration Wizard
Note SQL Security
Configuration Site
And there you go! of course I didn’t use best practices as using different accounts for some services or separating the DB server but anyway… if I manage to get some time I’ll further describe each step.
