Hello TRD10 and welcome to Seven Forums.
Here's a tutorial that should help to slipstream Windows 7 and create a bootable media. Slipstream Windows 7 SP1 into a Installation DVD or ISO File
Personal opinion (and others may disagree.)
Too many things can go wrong when slipstreaming. I think it would be better to "manually" get your computer up and running exactly the way you want it. Once that's done and you have all your programs installed, updates, drivers
, personalized all your settings, etc make a system image and call that your master copy. Keep it on a small external hard drive in a safe location. That image will restore your computer to pristine condition. Then get a second external hard drive (maybe 1TB) and make periodic system images once a week or once a month, whatever suits your needs. The more frequently you image the computer the more up to date the image will be.
With all the free imaging software available from Macrium, Paragon, EaseUS Todo, etc I think slipstreaming is no longer a necessity. But as I said, this is just personal opinion and others may have very valid reasons to disagree with me.
