I did it: http://www.ckode.dk/desktop-machines/how-to-enable-windows-edrive-encryption-for-ssds/ (enabled encryption using TPM module and BitLocker using SSD build-in encryption) and after that I changed BIOS to newer version. After that, BitLocker asks for putting recovery key, what I did. It is asking now every time for recovery key, but additionally system drive is not encrypted (according to BitLocker). Samsung Magician says that the third encryption option is enabled.
manage-bde -status in CMD:

- Lenovo Y700 with TPM
- Samsung EVO 840 in GPT
- UEFI enabled
- Windows 10 Pro
When try to enable system partition, then everything is ok, until Bitlocker asks for choosing how much drive to encrypt, what is wrong, because I wanted to encrypt not using software but hardware encryption.
I don't know what I need to do. I worry about reinstalling windows, becouse I worry about losing key and possibility to use drive. There was similar problems with BitLocker askig for recovery key, but I didn't see problem with used SSD.
