I am trying to install 11.04 alpha to a free set of partitions to try it out but neither the regular graphic installer or the alternate installer work.

The graphic one freezes when I try to boot the cd (or cd image on usb stick rather) with a distorted static picture of my regular desktop repeated four times. I have an nvidia 240 graphics card if that is any help in diagnosis. I think it is a matter of getting the cd image to use a low rez video mode but I have no idea how to force that. I have used both the iso's from the regular page and the daily page (for several days so far) and they all do the same thing. I have tried both the internal utility and unetbootin to set up the stick with the same results.

The alternate installer seems to work up to the point of the software selection step and then throws a 'failed step' error part way through.
