I am installing Ubuntu 14.04 on the virtual box, and after the installation completes, it says that the computer needs to be restarted to complete the installation. There is a restart now button beneath that and when I click on it, a error message appears that "oracle virtual box has stopped working". When I again open the machine through virtual box, it again asks for installation. Why is this happening?

I am using version 4.3.8 r92456 Virtual box and my host system is windows 8.

Also, when I open Ubuntu for installation, there is an option of trying Ubuntu without installing it. I clicked on that to use Ubuntu, and it was extremely slow on virtual box. This has happened earlier as well when I installed a previous version of Ubuntu, it was extremely slow and was lagging. I have enabled the 3D acceleration from settings, but I guess it doesn't help. What might be wrong?

  • What version of Virtualbox are you using, and what is the host system?

detach the ubuntu ISO file / DVD drive from virtualbox and restart it. this should suffice to get you back to ubuntu you have already installed.
