Re: installation on laptop with no CD or USB support
Not sure if it helps but, I've done this many times with my Dell laptops. As long as all the drives are IDE 2.5", I just switch to another laptop, install ubuntu in default settings (I mean like install but not put drivers that work only on that machine, like if you have nvidia or ati), then turn off, swap drive to end user laptop and boot-up.
So far has worked well, even when switching between manufacturers HDDs, last time I tried this was for a Compaq that had less memory than required by Ubuntu. It worked well.
