I installed virtual machine on my windows vista operating system and am running linux ubuntu. Then i downloaded virtual rails. i created a virtual hard disk as instructed called virtualrailz001.vdi. whenever I try to run the virtual machine I get the following error. Fatal: could not read from the boot medium. system halted from what I read in tutorials im supposed to have the VM mount a bootable ISO image to install the OS from. I cant figure out how to mount an ISO image…I thought I was supposed to mount the vdi image and how do I do this anyways I checked in the settings million times and there is nothing that says MOUNT… ---

do you have virtual box installed? if you are using virtual box, all you need to do is download the virtual image from [virtualrails.org](http://virtualrails.org), and mount the image as instructed on the virtual rails site. there is no need to install anything other than virtual box. Jason
