Hi Alan -
It would help to see a screenshot of the error message moved over so we can see what you're trying to run at the time. The error is not known in Windows 7, but sounds more like Lenovo being asked to generate another set of Recovery disks. Please clarify.
Your Lenovo Recovery partition runs from boot with the assist of the 1.46 gb boot partition so they both need to remain intact and undisturbed on the HD in order to run Factory Recovery, unless Lenovo now provides another option to save Recovery to external besides generating Recovery disks.
You can also always run Windows 7 backup imaging to save a backup image of your current state of the first two partitions. This built-in Windows 7 backup imaging also comes into play if you choose the best method of all which is to replace the inferior pre-installed Windows 7 with a Clean Reinstall - Factory OEM Windows 7
. Then Backup Imaging can become your own custom Recovery of a much leaner and better performing Windows 7 without the preinstalled bloatware and useless duplicate utilities which have better versions built into the Windows 7 OS.
Mull over these options and ask back any questions needed to help decide.
