Really? Can you please tell me how or post a link? From my research, i gathered that you cant install it remotely, and it wont boot off USB
if you mean win 7 or Vista (it doesn't work with XP) you can try the following link:

basically you need to get a trial version of parallels to install windows onto the bootcamp partition, then just as the VM is about to restart, stop it.
Afterwards, you need to fiddle around with the boot permissions, but give the link i posted a good read and it'll tell you what to do.
