I would like to find a software that can be installed onto a bootable device (USB stick / CD / DVD) and I should be able to backup my entire harddrive to an image and also restore my harddrive from that image all from this bootable software. In other words, I shouldn't have to have the backup software installed on the harddrive at all while writing/reading the backup images.
I don't need anything that makes automatic backups on regular basis, I want to do them manually when I want to.
I was using Acronis before and while it worked fine on my main computer, my other computer wouldn't recognize the bootable CD, it just skipped over it.
Can you please recommend some other software that could do what I am looking for? It needs to function on Windows XP and Windows 7.
