Hi Jonathon
Thanks for the reply!
I did try it and well i don't think it works, when i create the vhd and place the wim file in it, the machine boots but it just loads my primary os.
I was using sun virtual box and have since moved over to vmware workstation 7 to practice while reading the book. With sun virtual box booting from the vhd would just load a startup repair screen, now with vmware workstation it seems to work better.
I suspect my best option is to use wim2vhd, i just wondered if placing a wim file in a vhd would allow you to boot that image with out the like of wim2vhd.
Cheers
