I'm trying to install 11.04 but after a while it will start showing a stream of random characters on screen, then get stuck and finally open BusyBox. If I type exit there I come up with a "Panic occurred, switching back to text console" error and from there the loading won't progress. What's wrong?
Since your model isn't supported in the official list then I suggest you try an older version that is supported like 10.10 or 10.04 LTS.
it would make it easier to help you more if we knew the exact model.
I would guess from your tips that your model is Aspire One 532h.
We need a little more info, How far into the "install" are you getting? Can you boot to the LiveCD version?
As for an answer, I find when the installer fails, I found using the alternate installer will do the job.
