However, that is still not enough. Once you have created your recovery image, find it, rename it to INSTALL.WIM and then the following:
reagentc /SetOSImage /Path "D:\refreshimage\INSTALL.WIM" /Index 1
Change your path to wherever you created your recovery image from the linked post. Then use your recovery partition checkbox in the create recovery dialog should be available.
The advantage of doing a refresh image, is that it will include all the drivers and settings and core software installs for you. For your actual files either use file history or skydrive backups.
