I thought UNetbootin under Linux only allowed you to install a "live" Linux distro. Or have I misunderstood? And you would need a USB, which you don't want to use anyway.
It allows you to install to your hard drive and it doesn't have to be live. I haven't used the Linux version so maybe there is a reason it wouldn't work.
I tried UNetbootin and couldn't compile it for Vector. Installing VL6 Std on a Win XP eeePC , I "yank the hd out" like Overthere. Very simple and effective. Not very elegant but simpler than UNetbootin.
For me using unetbootin is much simpler than taking the hd out. Especially when talking about a laptop. Everyone's different.
