Hello!
So I have a Dell Inspiron m700 laptop with Windows XP Professional 32-bit Service Pack 2. I'm trying to run "sfc /scannow" but it asks for the installation CD.
I don't have any installation CD, but I do have a Startup Repair/System Recovery/Re-install Disc for XP Pro 32-bit but it's SP3. Can I use this in some way to reinstall/repair windows? If not, and I got a SP2 repair CD, would that work? If you need any other information that just ask!
Thanks!
