running windows vista: downloaded virtual machine and virtual rails  
cannot get virtual rails to mount to virtual machine

after downloading virtual rails i attempted to extract it so i could  
convert it to vdi file and this is the result  
virtual\_rails\_1.1(1).7z

i followed the tutorial at [http://www.virtualrails.org/node/3](http://www.virtualrails.org/node/3) to  
create a new virtual machine, but when I start the machine i get the  
error:  
FATAL; no bootable medium found! system halted

i googled and googled and read tutorials explaining that I have to  
mount virtual rails to virtual machine but in order to do that i have  
to convert 7z file of virtual rails to vdi file. is this correct?  
and if so i dont know how to do that. ugh!!!

What do you mean when you say “attempted to extract it”? Did you  
extract it? What did you use? Did you get any messages?  
A “7z” file is a 7Zip archive file ([www.7-zip.org](http://www.7-zip.org)), so if your file is  
still called that, I’d be curious that maybe it didn’t extract.  
You should have a .vdi file, which is the hard-drive from a VirtualBox  
machine.

Yup… still sounds like that hard-drive file isn’t correct.

Download 7zip, and (assuming you’re on Windows) right-click the 7z  
file and choose “extract here”.

PS I’ve just looked at the VirtualRails download page  
([http://www.virtualrails.org/node/2](http://www.virtualrails.org/node/2)), and it does say “Extract it with  
7zip or a compatible archiver” and links to the 7zip web page…  
always worth taking a few seconds to collect your thoughts when you’re  
having troubles with tutorials like these, and start again from the  
start.
