When I'm trying to install Ubuntu 12.04.2 in virtualbox on windows 7 host, it is getting installed. But, after pressing on Restart now button, the virtualbox is not responding and it is getting aborted.

I am using windows 7 professional and virtualbox-4.2.12.

Please help me with this. I'm facing the same problem with ubuntu 13.04 too. I have no other operating systems running in virtualbox

I have the same exact issue and the workaround is to power off the virtual machine after it's hung. Then start the Virtual Box again. When the install Ubuntu screen is up, close the window and then Ubuntu desktop will load. Then click on the power icon on the top right and then click on restart. When the system restarts, the installed Ubuntu will be loaded and you will be prompted to type in your credentials (if you have specified it in during the installation).

I also encountered this problem and worked around it in a slightly different way from Vijay. I'm running VirtualBox v4.2.18 on a Windows 7 64-bit host, and I'm trying to install Ubuntu Desktop 12.04.3 (32-bit) onto a new virtual machine.

After Ubuntu supposedly finishes installing and it prompts me to restart, I click to restart, and my virtual machine freezes. At this point, I go back to the main window called "Oracle VM VirtualBox Manager," right click on the virtual machine that is frozen, choose Close > Power Off, and click OK when I get to the VirtualBox warning about losing unsaved data. At this point, the virtual machine is powered off.

Next, I start the virtual machine and it boots again from the installation media. When I'm prompted to Try Ubuntu or Install Ubuntu, I choose Try Ubuntu. After that, the virtual machine loads into the trial version of Ubuntu. Once that happens, I click the top-right power icon in the top nav bar in Ubuntu (within the virtual machine window) and choose Shut Down. During the shutdown process, the machine prompts me to remove installation media, close the tray, and hit Enter. I installed from an ISO so I just hit Enter, and the virtual machine fully shuts down.

The next time I start the virtual machine, it boots into the full Ubuntu like I expect, and I'm able to go on and do other things.

I click reset, not power off if I have any issues –  davidbuddy9 Feb 8 at 18:54

It works when I just restarted the virtual system by selecting the shutdown option and again started the machine, this time it shows the log-in screen. Just enter the username and password which you gave during installation and login...
