    You can do a reset Bure and restore your Lumia to it's state you got it out of the box.
    (Settings / About / Reset My Phone)

    Providing you haven't updated it to a newer version of the operating system in Zune.

    Welcome along to WPCentral. :)

    Ok, but I want to totally wipe the phone and reinstall the OS from scratch.

    That will totally wipe your phone to an out of the box state, providing you didn't update it via Zune to a later version of the operating system than the phone came with.

    EG if when you got the phone and it came with Mango (7720) and you updated it with Zune to 7740, you will be stuck with 7740.

    It will totally wipe your phone though, you can't install windows yourself unless you flash a ROM onto your Lumia.

    (No idea if they are even available yet for Lumias)

    If you have used Zune to update, you could always try it's restore option.

    What problems are you having with your phone Bure?

    Why won't a reset do, if i may ask?

    Flashing a ROM is much more risky than the standard phone reset.

    I have flashed plenty of ROMS on my previous Omnia 7 but
    can't advise you about Lumia ROM flashing as i know nothing about what's
    available for it as it's relatively new.

    Do a reset before you even think about ROM flashing your Lumia. :)

    I got a Lumia today but it's demo phone so it contains om kind of demo OS (a demo screen saver etc), so I want to install a "clean" Windows version.

    I see, well I know very little about what's available for it.

    I think your best bet would be to have a look around the XDA Developers Forums Bure.

    Flash Lumia With Generic Firmware (debrand)? - xda-developers

    Good luck, hope you can find out more what you need to do there. :)

    There seems to be a few mentions of these demo phones around, I'm beginning to think people are nicking display models and selling them. Forums then get the aftermath/confusion to deal with.

    Ahhh that does make some sense then, my guess it was destined to be a demonstrator, 'til it was gifted to you.

    Is there any indication that the OS is gimped besides the demo screensaver?

    Yeah, every time one touches the phone so that the screen saver stops the phone indicates a new email when there is now new mail at all.
    And last night the phone reseted it self to its demo origin (I had installed my Exchange account, removed apps etc. and all this was gone in the morning)

    @op - to second what TheWeeBear said, try the hard reset before you try to flash a new ROM. You have nothing to lose - it just may work. If it doesn't, you can try the other options

    Settings / About / Reset Your Phone
