Recovery partion is normally f10 on startup. You can check if you got an recovery partion by doing the following:
Go to control panel then dubbel-click Administrative Tools then dubbel-click Computer Management then click on the plus by storage then click on Disk Management and it will show all the partions of the hard drives. There is normally one that is about 3GB. Some other laptop uses Alt + F10 at start-up. Did you get a manual with this pc?
