Hi,

Whenever I run sfc /scannow it asks for a CD. How can i point it to some other path where my installation source files reside.

Answer:

In Registry using regedit locate

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup\SourcePath

Set its value to the location where I386 foler is located. Provide the parent folder path of I386 and not of I386 itself.

Also update ServicePackSourcePath and add to Installation Sources as well.
