no task bar & howto install? USB boot on Lenovo Ideapad G50 notebook

Boots in UEFI mode from live USB in "guest" mode only. Sees my WiFi AP and appears to connect without errors. But not able to open any webpage in the browser. Also, I'm confused because there is no menu or task bar visible. I can only see 4 icons on the desktop. Is that normal?... the task bar only shows up after installation? I see no options to install it. help?
