I recently upgraded a client’s computer from an old spinning hard drive to an SSD (solid state drive) to make the machine much faster. A simple disk clone did not work for Windows 7 to make the disk bootable. To make Windows 7 boot properly, the SID (Security Identifier) had to be updated. This is done easily using Paragon Partition Manager by just checking off the option to change the SID after performing the disk copy.
