this backup would be of the complete operating system, so will this backup of my operating system work on another laptop of similar hardware configuration, what if I have given a password on booth as I have done now, will this help as a security? and yea I intend to do a backup on DVD around 5 of them.
The image CD can be attempted to be restored on another PC. However,
it "may" not boot up correctly since Vista has to be "activated" in
order to work correctly. This activation process uses several
"hardware" components as "flags" to determine which PC this Vista was
installed on. It is highly "unlikely" to have two PCs 100 % identical
so these "hardware" components would "probably" not be the same.
However, there are several imaging software packages that permit the
mounting the images as "virtual" hard drives in order to allow you to
copy files out from the image.
