Q: Bootcamp without Optical disc drive

Hi everyone. I want to install windows 7 on my iMac 24'' (mid 2008) but my optical disc drive is broken. I tried to install it with an USB flashdrive, but the system don't recognize it as a bootable device. I have the windows 7 ISO, vmware fusion, refit (i searched on the interet for the solution but i couldn't find any). thanks for help !

iMac, Mac OS X (10.6.8)
