Yes, your right. Taking an image is done from within Windows.
My images are kept on a second HDD, if I want to do a restore I put the boot disc in and it loads from there. I point it to which restore I want to use and away it goes. 12 or 13 minutes later all is back to the desktop. Takes longer from CD/DVD but works the same.
The screen is very "windows" like just the writing is bigger as the graphics drivers havn't loaded.
