I was using Windows 7 image creating wizard, but it has created just a bunch of files. I need an ISO file of the current system, how can I get it?
First of all, if you want to create an image from your current system you will need to boot your machine from another partition that isn't the one that you want to save. So, I would reccomend you to create a bootable CD or pendrive with linux, Clonezilla or even WinPE. So, after you have booted from one of these options you can save your partition image. I think the best program to do that is Clonezilla.
