Slipstreaming and Universal Install Disk

Hello, I am familiar with slipstreaming (in the XP world) and also how to make a universal install disk (in the Windows 7 world). What I can't get straight in my mind is how to mix the 2 procedures. What I would like to have is a universal Windows 7 install disk slipstreamed with SP1 and all updates. Can this be accomplished all in one go? If not, if I take a Windows 7 iso that has been slipstreamed with SP 1 and all updates, can I successfully create a universal install iso from that or will the fact that it has been slipstreamed prevent me from doing it? I hope someone can clarify this because I remember the misery I went through way back in my XP days. I spent countless hours reading and trying before I finally got it down. I sure don't want to go through that again. I have read countless Windows 7 guides but none of them refer to the procedure combined with creating a universal iso. Thanks.

I hope that someone will correct me if I'm mistaken, but I believe that it's not possible to slipstream WIn7 like it was for XP.

You can integrate updates, but the result isn't a real SP1 installer, and it can't be used to do a repair install on a Win7 SP1 system.

Thank you for your responses. I don't know why slipstreaming causes me so much confusion. I have read the tutorial on this forum several times. Slipstream Windows 7 SP1 into a Installation DVD or ISO File and still have a mental block. I'm sorry to appear so dense in all this. You have to use small words with me.

(1) Are you saying that if I have a copy of Win7 with sp1 (not slipstreamed) I can use this tutorial to slipstream the updates to make a new iso with which I CAN install windows but I CAN'T use to do a repair install?

(2) With the resulting slipstreamed disk could I then convert it into a universal install disk?

(3) Is the only way to do a repair install is to have an un-slipstreamed, original , non-universal disk?

For some reason I have never had much luck using SFC in Windows 7 so I have always just copied the user's personal files & done a complete new install using the universal disk I have already created & then downloading all the updates but this really takes a lot of time and effort especially when I don't always have access to their applications. Every once in a while I have been successfull doing a non-destructive repair install. I think the key to whether or not I have success is in the disk that I use. I don't have copies of each individual versions of Windows 7 both with and without sp1. To be honest, I don't understand all the exceptions involved with what will work, such as whether or not sp1 came preloaded or was installed through Windows update. I am looking for the best method that takes the least amount of time without losing user data. What are your suggestions? Why oh why can't it be as easy to repair an unbootable Win 7 system as it was with XP.

There's no reason to do this now that we're allowed to link the official Win7 installers with SP1, unless you want to slip in the later updates since SP1. But this would lose the ability to Repair Install so it's a waste of time.

A better approach if you want an installer that's complete as you want it is to transfer images of your idea setup using Acronis True Image with Universal Restore, by first SysPrepping to move image to another computer, or by adjusting an image to boot on different hardware using Paragon Virtualization Manager.
