I have Acronis home installed and have made backups of both "My Computer" & My Documents" These are stored on an USB driven external 80 MB portable hard drive. Despite reading the .pdf instructions document, I still am not sure exactly how to carry out a restore. If I have to/want to format my HD how do I go about restoring the "My Computer" backup, which should include the Windows XP operating system? Surely Acronis must be installed as a program on the PC's HD before being able to restore the backup. This means that the Windows XP O.S. must be re-installed first does it? My PC's H.D. is only 40 GB, so I think the "Snap restore" feature, whereby a new partition needs to be created on it to store the Acronis snap restore informtion, is not viable. Is this a fair summary, or is there a really simple way to reformat my PC's HD and restore the whole lot of saved data,without first re-installing XP?
