Hi there.

Just to let you know ( maybe somebody, get the same error and can use the Info ) that I found the course of the error.

I spend 4 - 5 hours today trying to find a website mentioning that problem and finally I succeded when finding the following .........

" The error occur if the file " win51ip.sr1 " ( it's in the XP Sp1 .exe file) is missing from the Root of the Slipstreamed CD, the file prevent the installation from asking for "The Windows XP Professionel Service Pack 1 CD ".

To check if that was the case, I copied the XP CD to a folder on my HD - unpacked the SP1 file and copied the win51ip.sr1 file to the Root of that folder, burned the CD and rebooted.

After rebooting I did a test to check if the Error occured. Inserted the CD in the drive and tried to Run " sfc/scannow " ( have failed before ) and Jubii no error message about a wrong CD.

Have a nice Day / Evening
