This is a problem with the Ubuntu Image, not with the Virtual Box package that is being distributed.
I had similar symptoms, so I went to Windows XP and installed the last version of VirtualBox Free Edition (not Open Source). I tried to boot the Lucid ISO (and yes the checksum was ok). The initial menu came out OK, but after selecting "Try Ubuntu without Installing" or "Install Ubuntu" all I got was a black screen with a white underscore on the upper-left corner. Maybe this has something to do with the introduction of Plymouth? -- virtualbox: Lucid alpha2 does not boot https://bugs.launchpad.net/bugs/508777 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
