I've bought used macbook pro (mid 11) and wanted to reboot system.
I disabled all functions and tried to reboot whole system. Previous owner disabled his appleId. Also he disconnected this macbook from his appleid profile. But I cannot download MacOs from Appstore (there is no such object (Yosemite). Also I downloaded from the official web file system but macbook doesn't see USB. What should I do?
You need whatever OSX came with the notebook originally. I don't know the details of that model but it was probably Mountain Lion. After that your only option is to upgrade to El Capitan. Apple has pulled Yosemite from distribution which means only if you log in with an Apple ID previously used to download Yosemite when it was available can you re-download it.
About macOS Recovery - http://support.apple.com/kb/HT4718 - "OS X Lion and later include OS X Recovery. This feature includes all of the tools you need to reinstall OS X, repair your disk, and even restore from a Time Machine backup." - Also information about Internet recovery.
