My main boot drive is failing slowly, so I've bought another drive to replace it. I'm trying to just replace the boot drive with the new drive, but I'm having issues along the way. I've used Norton Ghost to copy all the files from the boot drive over to the new drive, then just swap the drives out. Whenever I do this, it won't boot windows, it just gives me the message "No OS Found, Press any key to boot from CD". Same thing happens if I use DOS utilities to copy over all the data to the new HDD and swap the drives. I've even gone through, moved all the data to the new drive, and gone through Regedit to change the drive letters so that the new drive is drive C:, then turned the PC off, swapped the drives, and tried to boot like that, but no dice. What am I doing wrong here? What is the proper way to successfully copy and replace your boot drive?
