The mere fact you're asking makes this whole process open to your abilities. I hope the backup is already done and on some media other than the bad HD. Also, whatever method you did the backup "provides the means to restore" the backup. That's the other half of backup, its part of the whole process, otherwise its useless. Your details are slim to almost none, so what have you done?
Also, a backup is done under one of two methods, either return to day 1, the day you brought it OR return to the day you did the backup of the PC as it was on that day. Which did you do?
my hard drive had sectors go bad and i need to replace it. Some information is no longer accessable.my question is, can I use my system backup to restore to a new drive and, if so, how do I do it?.
