Hello,
Just to report how I installed Ubuntu 9.10 Alpha 4 using my Pendrive. First I download it from http://cdimage.ubuntu.com/releases/karmic/alpha-4/
After this I used the “System – Administration – USB Startup Disk Creator”, choosed the image that you want and press “Make Startup Disk”.
Than just boot from the PenDrive and install normally.
