So my computer has the message Press Y to reset fTPM, if you have bitlocker or encryption-enabled system, the system will not boot without a recovery Key
Press N to keep previous fTPM record and continue system boot, fTPM will NOT be enabled with new CPU unless fPTM is reset (reinitialized), You could swap back to the old CPU to recover TPM related keys. Whenever I press N nothing happens, what do I do?
