Thanks for help. I am not real good at downloading and installing and I am not sure I need to do that.
I will go to start. I purchased the Raspberry Pi Model B pre-installed with Noobs (not sure what that is).
Anyway got that up and running. Then was at a bit of a loss what do next until I. read about Raspbmc which
I could use as a media player.
I then purchased a kit with all the needed bits and pieces including a4gig SD card loaded with Raspbmc.
all went well and it seemed to be booting up ok until a box came up on the screen (no mention of a box in the instructions) the box contained
several options and one of the options was go to desktop on booting this seemed ok to me so i ticked it.
this is where I am up to as I stated I want to see the bar from which which I can add video files and music.
Question is is there some way that I can do a fresh load from the SD card.
