Imaging software with boot option

[pioneerx01]

Hello,

I am looking to buy and imaging software that I do not have to install, just pop the disk (or USB stick) in let it boot image the entire drive to external device.
When the PC crasher or I just want to start again I want to boot from the disk tell it where the image is and restore the entire drive to square one.

I am looking for software that does not have to be installed, just booted from.

Thanks

Acronis True Image, just boot from the CD.
