How to create Windows server 2012 installation disc/Bootabel DVD from pre-prepared source directory

Below is a guide on how to create Windows Server 2012 installation disc from pre-prepared source directory. The source directory should include all files of Windows Server 2012, which looks like below screen shot.

1. Start PowerISO.

2. Click "Add" button to add all files and folders under the source directory to current compilation.

3. Click the menu, "Action --> Boot --> Add Boot Information...", and select etfsboot.com, then click "OK" to add it as boot file. 'etfsboot.com' can be found in the boot folder under the source directory.

4. Insert a blank DVD disc in the writer, then click "Burn" button on toolbar to burn the current compilation to the disc. 

If no errors occurred in the above process, you should now get a new Windows Server 2012 installation disc.
You can also save current compilation to get a bootable ISO file in step 4. You can burn the ISO file later to get the Windows installation disc.
Windows 8 and Windows 7 installation can also be created using the similar way.

4. If you want to specify an alternative source file, in the Alternate source file path box, specify a fully qualified path of a shared folder that contains the contents of the \sources\sxs folder from the installation media. Or, specify a WIM file. To specify a WIM file as an alternative source file location, add the prefix WIM: to the path, and then add the index of the image that you want to use in the WIM file as a suffix. The following are examples of values that you can specify:
   1. Path of a shared folder: \\server_name\share\Win8sxs
   2. Path of a WIM file, in which 3 represents the index of the image in which the feature files are found: WIM: \\server_name\share\install.wim:3
5. If it is applicable to do this, select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) check box.
6. Tap or click OK.
7. At an elevated command prompt, type the following command and then press Enter to apply the policy immediately:
