I downloaded the SP SP3 install file from Microsoft and installed it on my machine. During the install I got an error message saying that it couldn't copy NTLDR because it couldn't find the file. The file was in the folder that it pointed to. Nevertheless, I copied it to the desktop so I would have it, and went on with the install. Things seem to be working fine, except for my normal scheduled late night shutdown after a virus scan and backup. The NTLDR file in the C:\ drive and the one from the service pack are different when I run a compare. I could probably replace the NTLDR file by booting from a BartPE CD, but wonder if this would cause huge problems. Has anyone had this issue with the install?
