Laptops :: USB boot ok, but installation not :(

Ok, I did all the steps for preparing the USB (512Mb) for DSL and everything went ok until when I booted, the installation setup freezes at "searching for for USB"... and nothing else happens. I've tried it several times and still the same thing, my CAPS LOCK key is activated and nothing but a plain reset helps it at all.

I tried loading the emulation from the USB under windows and it loaded perfectly... so dunno what's the problem with it.

My pc is a laptop Packard Bell EasyNote with AMD Semprom 300+ at 1.8GHz, 1024 DDR RAM and ATI Radeon XPress 200M 256Mb
