Windows 7 system is installed on disk D. Problems after disk replacement

Laptop, original GB hard drive, divided into two areas: c, d;
2008 server is installed on drive C and Windows 7 is installed on drive D;
I bought a 2008 GB hard disk and divided it into two zones. I used the hard disk clone tool to clone the data to the new hard disk. The server can be started normally, but it can be started in windows 7, it cannot be used. I found that after entering windows 7, the original D disk was changed to a C disk. Why did I find it?
First, Download Windows 7 automatic installation kit (AIK)

After downloading and installing, put the Windows 7 installation disk into the optical drive, open the Windows automatic installation kit (AIK) for Windows 7, follow the Wizard to create the PE boot disk, and then start the PC with the PE disk with the production number, after entering, you will see the prompt:

Click "yes", restart, and enter the original Windows 7. Everything is normal.
