I'm pretty new to all this so ill show you my train of thought as best I can. Images are in the attachment.
I used 'Wubi' the windows installer to download Ubuntu 12.10 everything is fully loaded and it asks me to reboot. When it comes back to life my computer has nothing but a white flashing '-' symbol.

I turn my computer off and on again and it asks me if I want windows 7 or Ubuntu I select Ubuntu and this shows up..

In conclusion, what should I do with this, baring in mind I know absolutely nothing about computers. Thanks for any help
