How it looks when its booting up from bios

My friends display looked similar on his windows 7 setup, looked fine once installed though...

That looks like setup is being forced to use very few colours. It will probably be fine once you have got the proper graphics drivers installed and you can increase the colour depth.

Every OS installs like this if there are no standard gfx drivers that will do.

Just install as per normal - it is fine. To be expected really :)
