I've downloaded the VirtualBox Image for OBIEE 126.96.36.199 - Sample Applications v107.
I have Windows 7 64 bit in one partition and Windows Server 2008 Standard Edition in another partition.
1. Which OS is good for installing this VirtulalBox Image?
2. When I install VirtualBox software, should I select the Networking features? I'm not sure if I need it since I will only be running this in my computer for evaluation and learning. It seems it will create network adapters and I don't want it to mess up other settings in my PC.
I don't know if it helps since it was posted long time ago but I'd suggest to use windows 7 (64 bit) since it the virtual box with the sample App seems to work quite well on it. Also I am not too sure what you mean with the network features but certainly the virtual box would create a network called Virtual Box Host but it doesn't mess up (change at all) your other network connections.
