How to access the recovery partition on a Lenovo m58p?

Well guys i recently bought a Lenovo m58p that came pre installed with windows 7 home premium however in order to try and make the most of the hardware that i had on hand i decided to install windows XP on it. However, doing so allowed XP to over ride the boot loader thereby removing the recovery option that came on during boot up. Now, the partition is still there however i see no way of getting into it. Would anyone know how to rewrite or reconfigure the boot loader in XP to gain access to that recovery partition?
