Hi, Have you ever set up en_windows_server_2012_release_candidate_datacenter_virtual_machine_x64 within Virtualbox? I have got this issue when attaching such exe file to IDE controller. Is this not a suggested way to attach the exe file? Many Thanks & Best Regards, Hua Min

After you download the compressed VHD (comes as self extracting *.exe) double-click it to extract the VHD file. Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows] Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Thanks. BTW, do you know such OS is fine to run .Net 2008 express inside with IIS?Many Thanks & Best Regards, Hua Min

I haven't used virtualbox so I don't know either. Might want to ask them here. https://forums.virtualbox.org/viewtopic.php?f=2&t=37628 Regards, Dave Patrick ....

Thanks. Do you or anyone know if VM is better to use for running Windows as the guest?Many Thanks & Best Regards, Hua Min

Might ask them here what they're using. I'm sure it will run fine on VMWare ESXi if that's what you're asking about. http://social.technet.microsoft.com/Forums/en-US/winserver8setup/threads Regards, Dave Patrick ....

OK, thanks. Could anyone please help me change chipset above?Many Thanks & Best Regards, Hua Min

Try Chipset: ICH9 Also, it's better to ask Virtualbox related questions in their own forum https://forums.virtualbox.org/viewforum.php?f=6&sid=e013f19b1d4c48f1a99c06c5d9e78914 Thanks I do not represent the organisation I work for, all the opinions expressed here are my own.
