doubtful, you more than likely will have to make new image and just add the service pack. how did you slipstream your image? RT7lite?Anyone know if there is a way to install this on a slipstreamed version of W7? I get an error saying I don't have the right components when I try to install it. I don't want to reformat just for the SP if I don't have to.
pays to use the integrated image instead of slipstreaming it appears
The images are universal except for a configuration file "ei.cfg" which controls the default installation. This can be altered to any version or disabled to allow selection by menu.
