Well, I have seen it before. The internal DVD drive might be worn out and doesn't properly read DVD disks anymore. Copying Windows disc on a new media won't make any difference. In that case you either use an external USB DVD drive for the installation or create a USB flash drive as suggested. Another option (I used for installing Windows 7 to really old PCs that would not boot from DVD or USB) is to remove the disk, put it in another computer and install Windows there. Then put it back. Alternatively you can deploy Windows using Dism or GimageX utilities. These extract the Windows files from the install.wim file inside the sources folder and copy them to the disk. Then you have to make the disk bootable (mark the partition active) and install Windows boot loader (with the bcdboot command or otherwise). You put the disk back on the target computer and you resume Setup. It is like Setup has already copied all the Windows files to the disk and did the first restart. Setup resumes with the installation as if it had been started locally.
