Disk Imaging and Rescue CD

From what I can see, disk imaging is storing your system data in a detachable drive (since I read it can't be on the drive you're imaging) and a rescue CD basically is made so that if you have a crash, you can pop that **** in and you can boot from it and it will save your pc. Is this all right?

Its more of a portable copy of your exact OS. a bootable copy for that matter. A disk image is usually formatted in an .iso format. If this 'rescue' cd can mount drives, then yes, it can restore a broken system.

The important bit is if the restore program on the bootable rescue CD can see the HD in the machine. When you make the backup image, you are running Windows. The Windows driver for the HD controller is running. You need to verify that the boot or rescue CD has a driver for the HD in question. Most often you can do this by downloading the trial version, or free version of an image backup software such as Macrium Reflect or Paragon Drive Backup, and make the Linux Rescue CD. Do an image backup. Then boot the Rescue CD and start the restore program. If there's a problem you will usually find out before even actually starting the restore process(such as the restore program won't be able to see the HD in the PC or it can only access it in super slow compatibility mode.)

Best to find out before relying on it.
