I was running 11.10 and wanted to upgrade to 12.04. After it downloaded all the files, it was loading something (this was before the installation started) and the light went out. Now when I turn on my computer and boot up Ubuntu, I just get the logo and it stays there forever. Not even the recovery mode works. I tried booting up from a CD to access my information so I can back up and delete the one I have, but when I try to access the drive it says I do not have permission. Any ideas on how to solve either of those problems? Thanks
