If for any reason you have the same problem, the way to fix it is the following:
1. Boot your computer from Windows Installation DVD.
2. Select the “Repair computer” option.
3. Exit the wizard by clicking “Cancel”. This will take you a menu with various options.
4. Click “Command Prompt” in the menu.
5. Here you should switch to your DVD Drive. If you are not sure which is the DVD drive letter, you could experiment by trying each one of them, or you could use the DISKPART command and then LIST VOL which it will give you a list of all drives on your pc, similar to this:
