Cloned drive will not boot

Thread needs solution

I've been using Disk Director for years and never had a problem before. I have a Win 7 system with 2 drives

C: is 80gig and E: is 500gig

When I start Disk Director from a CD, one thing that looked wrong was that both drives show a primary partition with green bars, I expect only the first physical drive to be like that and other drive to have a small amount of unused space at the start. My son set up this machine a while back and its been running fine, so I ignored that.

Cloned the C: 80 gig to a new 250gig drive in an external case, and set drive letter K: to the old drive and C: to the new one. At completion it rebooted and appeared to boot from the newly created external C: drive coorrectly. Shut down and pulled the old drive and installed the new. BIOS shows drives correctly, but Windows will not boot - does not even attempt to start, just fails.

Reboot to DIskDirectory and it looks ok, except neither drive is assigned a letter and there is no option to assign drive letters.

Hello Bob,

please follow this instruction to repair your system:

1) switch off the machine;

2) connect the old drive using external case and put your new drive in the place you are going to use it;

3) boot from Acronis Disk Director media, change old drive letter to C: again;

4) start cloning to a new hard drive again, please make sure that "Copy NT signature" check box is selected;

5)  after the clone process finishes you will be offered an option to shut down the computer by pressing any key. This enables you to remove the old hard drive.

6) after you remove the old drive please check if your system can be correctly cooted from a new drive.

Thank you.
