I'm currently using Ubuntu 9.10 with VirtualBox 3.2.4 and I'm trying to install Windows 7 Ultimate 32-bit and I'm having the same problem. I was able to do it fine with fixed disk. However do to my testing that I'm doing I would like to really get it to work with the dynamic disk. I hope this problem gets fixed. Yes, you need an ISO or cd of the os that you want to install inside the virtualbox. VirtualBox supports 64-bit guest operating systems, even on 32-bit host operating systems, provided that the following conditions are met: You need a 64-bit processor with hardware virtualization support. We are using win 7 32bit.

The VirtualBox Extension Pack adds useful new features to this popular virtualisation package.
Virtualbox 32bit Win7
It includes a USB (EHCI) controller, for instance, which should allow you to get better performance from your USB devices. You'll probably need to enable the controller manually, though, as well as add filters for the USB devices you'd like to use (the VirtualBox manual has more details).
You also get VirtualBox Remote Desktop Protocol (VDRP) support. Essentially this allows you to run a virtual machine on one PC, while you view and control it from another: again, the manual has the full story.
And there's also support for remote booting a computer through emulation of the Intel PXE boot ROM with support for the E1000 network card.
None of this requires separate installation, as the extension pack has a 'vbox-extpack' file extension that's handled by VirtualBox. So close down VirtualBox, download and double-click on the extension pack, and VirtualBox will launch and install it for you, upgrading any earlier version you might have.
