Windows Server 2008 64 Bit on VirtualBox installation issue.

I’m just starting to explore SQL Server 2008 Clustering and hit this issue when trying to install Windows Server 2008 (64 Bit) in VirtualBox. The below screen, with "Windows failed to start" error, reared its ugly head shortly after booting off the ISO image.

virtualbox windows failed to start Status: 0xc0000225 Info: AN unexpected error has occurred.

Thankfully the solution is quick and easy (once you’ve found it) so I’m posting it here for clarity.

Close the virtual machine and return to the main VirtualBox screen.

VirtualBox

Select the appropriate virtual machine and click the Settings button. Click the System icon on the left and check the box labelled "Enable IO APIC" on the Motherboard tab.

io_apic

Click the Processor tab and check the box labelled "Enable PAE/NX".

pae_nx

Click OK to save the changes and restart the virtual machine. Your installation of Windows 2008 Server (64 Bit) should now progress. Fix for this dug out of a VirtualBox forum thread.

    Thank you! This works for Win7 64bit too.
    I went through 5 tutorials on getting Win7 installed on dropbox, and none of them explained why it was failing. The tips here worked.

    Hi Bev,

    Not quite sure what you mean. Are you saying you cannot access services running on your VirtualBox VM? If so go to Settings > Network > Attached To and change this to “Bridge Networking”. See here for details – http://www.virtualbox.org/manual/ch06.html

    Cheers,

    Hi Mathew,

    I’m far from being a VirtualBox expert but I can have a go. I’d need more information. What have you done and what is the exact error message?

    Cheers,

    It would seem you haven’t enabled 64Bit support for your VirtualBox CPU. Similar issue here http://superuser.com/questions/324027/why-do-i-get-this-cpu-is-not-compatible-with-64-bit-mode-on-a-64-bit-processor

    Aaaaaww thanks you so much, this was driving me nuts ..
    Worst part is i didn’t change a single thing since the last time i installed a W2K8R2 on a VM and was wondering what a recent update did to this situation.

    Again, thank you.
