Apparently, I can use a folder called 1386 to mend my XP....but going through this tutorial below....i don't have the last Key? ...............

"Step 1. If the folder does not exist then you can make one: You will need to get your XP CD and locate the folder called i386 (I386) This is a major folder and should be one of the first you see, now copy this onto your hard drive into the system root. For most of you that is going to be C:\ so you should end up with a folder that looks like: C:\I386

Step 2. NOTE: Carrying out this operation may entail altering the registry, so you should "Back it up" first. From the Start Menu select "Run..." type "regedit" (without the " " quotes)

Now you will need to tell your computer you now have the files on your PC. We do this is the registry by navigating to:

HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Setup

You will now see various entries here on the right hand side. The one we want is called: "SourcePath"

It probably has an entry pointing to your CD-ROM drive, and that is why it's asking for the XP CD. All we need to do is change it to: C:\

Simply double click the SourcePath setting and a new box will pop up allowing you to make the change.

Now restart your computer and try "sfc /scannow" again!
