Hi. I am trying to upgrade to a larger hard disc, transferring data using ATI’s backup and restore features. I have done a full backup of the system disc (disc option ticked, just one partition on it) but when I restore the image to the new (larger) disc the system won’t boot from the new drive. When I attempt to boot from the new disc the PC first displays a dark screen with a large Windows logo (with three dots running across the screen below the logo), then a blue screen with a small Windows logo, then a blank blue screen. From this point on the display remains unaltered, but after an extended period (a few minutes) the sound effect associated with Windows starting up is played. After a few more minutes the sound of Windows closing is played several times in succession (with about 30 seconds between each playback). The PC then reboots and the process repeats in a loop. After the restore operation I have tried; Rebooting with both the original and new discs installed but with the new disc selected as the primary boot disc. Rebooting having disconnected the original disc. Rebooting with both discs in place, and with the original disc selected as the primary boot disc, then rebooting with the original disc disconnected. Each of these options has been tried with a fresh backup and restore operation. In each case the re-boot after restore has been attempted first without restoring the MBR, then restoring the MBR to the new disc and attempting to boot from the new disc a second time . Each option has also been tried with the new disc connected to the same SATA port as the original disc (i.e. making it disc 0) and with the new disc connected to the same port as when the restore operation was run. Cloning the disc works perfectly, which would solve my immediate problem – but I would obviously like to get the restore operation working now, when it isn’t vital, so that it will run OK if it is ever needed. My knowledge in this area is limited, but I seem to recall experiencing similar symptoms in the past when I cloned a disc, did not disconnect the original disc before rebooting, then attempted to boot from the new disc. I believe this problem arises due to a conflict between the disc identity and the disc identity recorded in Windows (I am hazy on the details). Could something similar be happening with my restore operation? Does anyone know what might be wrong? It would be great to solve this problem with the benefit of some knowledgeable advice – this is really starting to take up a lot of time. Thanks.
