I haveinstalled oracle VM on windows 7 [32bit]. Then I have tried to install Ubuntu 13.04 version. At the end of ubuntu installation, it asked for restart but when I clicked on the restart button, error appeared.
Error message appeared as follows:
VM manager stopped working.
How can I solve this problem??????
I have repeated the ubuntu installation but the result is same.

Please help me to install ubuntu
