usually a new laptop would come with instructions on creating a recovery
CD...hell they usually prompt you to do so as soon as you start the thing.If
you have no CD then you have a recovery partition somewhere on the HD.
Please take the time to read the manual that came with the machine and it
will explain how to make that "recovery" CD.
Or if you really have no such mechanism preinstalled on the laptop might I
suggest Acronis True Image..
http://www.acronis.com/
it allows you to "image" your HD contents....helps you create an emergncy
start up CD.....Allows you to do backups...
By buying another HD and a USB HD enclosure you could image/clone your
present HD to the New HD...this way you would have a copy of the original
install.You could update the image/clone every so often in order to keep it
up to date.
If something crashes the Acronis Emergency start CD will load a running
version of True Image which has the capabilities to "restore" that saved
image.If the HD breaks after the install of a new HD you could do the same
thing.
