It’s always frustrating when we want to install a Windows component and Windows asks to insert the Windows CD-ROM. Here’s the trick to stop Windows asking for a CD-ROM. If you have some space in your hard drive, then you can copy the i386 folder located in the Windows CD-ROM and then change the path of
Windows installation source to that location. Go to Start –> Run –> regedit –> Navigate to the following key:
In the right hand pane, double click the “SourcePath” key. It will be most probably currently showing the path to your CD-ROM. Mine is G:\. Change it to wherever you put your i386 folder i.e., D:\i386. Now Windows will automatically copy the required files from the i386 folder. You will not be prompted for inserting a Windows CD-ROM.
