I have a pretty weird problem with Ubuntu 11.10. I am using a Live CD of it to install it alongside Vista, but when I click on "Install alongside Windows Vista", it just resets. I've tried installing Ubuntu 11.10 before, but it gave me a black screen after booting my laptop up and choosing Ubuntu from the GRUB menu, so I deleted it's partition and now I'm trying to install it again. What should I do?
I would try burning the Live CD again. Sometimes there can be small errors that cause problems like this.
Other than that I imagine it could be any number of things.
