I upgraded my Ubuntu OS on my laptop from 11.10 to 12.04, I did the Virtual Box work arounds mentioned in the thread: VirtualBox doesn't load after 12.04 upgrade, My Turnkey Linux VM's are back up and running now however my windows 7 VM has failed to come up. My whole laptop freezes and i have to force restart my laptop each time I try to start my windows 7 VM.

Is there a work around to ensure smooth startup and running of win 7 VM's

My virtual box version is 4.1.12_Ubuntu r77245

The probably-related VirtualBox bug ticket says it is fixed in VirtualBox source, and also details a workaround via grub.

Hopefully the patch will be applied to Ubuntu-12.04 .

What are your Ubuntu and Windows versions (including 32 bit or 64 bit)?

I also had some problems when setting up VirtualBox 64 bit Windows machine on 32 bit Ubuntu, but everything works fine with 32 bit Windows.

  • The Windows I have is 64bit and the host ubuntu is 32. The same setup was there in 11.10 and things worked just fine. After I upgraded to 12.04 this issue is occurring. – darkliquid May 04 '12 at 08:32

I had the same problem; 64bit version of Windows 7 machine on 32 bit Ubuntu 12.04. failing to startup with Virtualbox 4.1.14

This setup worked perfectly until I upgraded from Ubuntu 11.10 to 12.04

Removing and reinstall Virtualbox did not solve the problem:

    sudo apt-get remove Virtualbox-4.1
    sudo apt-get install Virtualbox-4.1

ALSO executing:

    sudo aptitude update
    sudo aptitude install dkms
    sudo /etc/init.d/vboxdrv setup

At last I created a 32bit version of Windows 7 machine and it works with fine without any problems.
