It looks like that system is properly recognizing the software CD and process of installation proceeds correctly.
So possibility of having some software error is too low.
The Installation might discontinue if the system cannot copy files from the CD.
It is therefore possible that the Windows installation disk you are using is scratched, grubby, or dirty.
Clean the disk with a soft cloth if it is dirty or grubby and insert it in the CD or DVD drive.

Begin the Windows installation again with new and/or same CD after cleaning and check carefully the whole process.
