What dist to use?

I have a situation as follows and was hoping someone here can help me with my little problem.

I work in a store that sells computers. We have one of each model we sell on display in the store wich means every time we get a new model I have to install the windows on it so people can see how it looks. Wich also means every time we sell the last one of a model we have to reinstall it to ensure that the customer gets a freshly installed computer.

What I want to have is a dist that runs solely of a cd/dvd so I can just connect the new pc, insert the disc and have the comp boot of it and start and loop a videofile of my choosing.

Is this possible easily with any linux dist? I have very little experience with linux myself so if someone knows of a good dist and/or can help me with how to do this I would be very grateful.

Hi and Welcome !

You can use any LiveCD having Proprietary Media Codecs pre-installed. I would suggest you to try SLAX. Burn .iso image to CD and boot up from It. It supports all media formats.

Here are a couple of sites where you can check out many of the existing Linux liveCDs:

DistroWatch.com: Put the fun back into computing. Use Linux, BSD.

Let us know how it goes.
