MacOS – How to recreate Lion Recovery HD partition

filevaultmacosrecovery

I have a Macbook Air Mid 2011 which came pre-installed with Lion.

After a trackpad hardware problem I wanted to be sure that none of my programs was responsible for the problem. I booted into the recovery partition and used the disk utility program to repartition the disk with a single partition (the recovery partition wasn't listed there so I assumed that it was not affected of the repartitioning much like the hidden EFI partition) and reinstalled Lion onto that partition.

Later I noticed that this has in fact removed the internal recovery partition (although it allows the "web recovery" to start).

Now I'm searching for a way to "restore" that internal recovery partition. Is there a manual way to re-enable that partition? Or any other way to allow me to use Filevault 2 (which requires the internal recovery partition)?

You can recreate the Lion Recovery Partition by following the instructions available at this Apple support document: http://support.apple.com/kb/dl1433

Note, you are not supposed to be able to see the recovery partition in normal use, so can you clarify how you have identified it is missing? What happend when you boot with the CMD-R keys held down?
