I'm running Windows7 Enterprise, x64 version. I've created a windows7 vhd file with help of the following blog post hanselman blog

After that, I've added it to my boot menu with help of another blog post hanselman blog

This worked great.

After that, i've upgraded my hdd. With help of clonezilla i've copied the old disk to the new disk. Next step was to copy the vhd to another partition.

Then i updated the boot menu. However, the step

C:\>bcdedit /set {guid} device vhd=[driveletter:]\<directory>\<vhd filename>

fails with the message

An error has occurred setting the element data.
The request is not supported.

what is happening?

Finally the problem is clear: the copying of my old hdd created dynamic disks instead of basic disks. After changing this everything worked again.

Windows 7 Support's Native Boot VHD, but BCDedit does not Support Dynamic Disk, This error means that you have your VHD in a Dynamic Disk or Volume. You can Convert Your Dynamic Disk to Basic Disk in order to Continue.

Have you tried EasyBCD 2.0? It has a new feature for automatically adding VHD entries to the BCD.
