Here I want to share about this problem that I found during formatting and install windows XP into my PC. I have done this many time but I never found this problem. During formatting, it format the hard disk fine, but when starts to copy files, and then it goes show the following error.
Windows XP Professional Setup
The file xxxxx.dll was not copied correctly.
The file Setup placed on your hard drive is not a valid Windows XP
system image. If you are installing from a CD, there may be a problem
with the Windows XP CD.
