In case you want to reinstall Windows or repair Windows, it is desirable that you have a bootable disk of Windows. WBI Creator (Windows Bootable Image Creator) is a freeware app for Windows which lets you create a bootable ISO for Windows XP, Vista and Windows 7. The app is portable and does not require any installation. You can easily create the bootable ISO by specifying the set up files of Windows.
You just need to specify the label and the set up location. Also select the OS type for which you are trying to create the ISO. The output path for the ISO can be specified.
Once the ISO image is created, you can burn this file into any DVD using the normal DVD writing tool or the default ISO burner available in Windows 7 as well. WBI Creator is a simple tool for users who do not know how to create a bootable disk for Windows.
