2. Decide whether to erase (format) your disk

3. Install macOS
When you're ready to reinstall macOS, choose Reinstall macOS from the Utilities window. Then click Continue and follow the onscreen instructions. You will be asked to choose a disk on which to install.
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer is for a different version of macOS than you expected, learn about macOS Recovery exceptions.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.

- If macOS Sierra 10.12.4 or later has never been installed on this Mac, Option-Command-R installs the macOS that came with your Mac, or the closest version still available. And Shift-Option-Command-R isn't available.
- If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might offer only the macOS that came with your Mac, or the closest version still available. You can upgrade to a later version afterward.
- If your Mac has the Apple T2 Security Chip and you never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
- If you just had your Mac logic board replaced during a repair, macOS Recovery might offer only the latest macOS that is compatible with your Mac.
If you can't get macOS Recovery to offer the installer you want, you might be able to use one of the other ways to install macOS.
Other ways to install macOS
- You can also install macOS from the App Store or Software Update preferences. If you can't install macOS Catalina, you might be able to install an earlier macOS, such as macOS Mojave, High Sierra, Sierra, El Capitan, or Yosemite.
- Or create a bootable installer disk, then use that disk to install macOS on your Mac or another Mac.

About “The drive where Windows is installed is locked”
The following information on this error has been compiled by NeoSmart Technologies, based on the information gathered and reported by our global network of engineers, developers, and technicians or partner organizations.
Description and Symptoms
The error messages, alerts, warnings, and symptoms below are tied to this error.
Symptom 1: “The drive where Windows is installed is locked” error screen on startup
The screen below is displayed when you attempt to start your PC. Unlike most errors, this error screen isn’t identified by an error code like the “Your PC needs to be repaired” error:
Causes of this Error
This error has been known to occur as a result of one of the following causes:
Cause 1: Bitlocker boot agent disabled
The root cause of this issue is due to the usage of Windows Bitlocker encryption. Bitlocker is a whole-disk encryption used to secure user data, but requires that the Bitlocker boot agent be installed. At boot time, this boot agent is used to unlock the Windows drive before attempting to load Windows 7, Windows 8, or Windows 10. If this agent is disabled or overwritten, either on purpose, by accident, or due to 3rd party interference such as 3rd party bootloaders or malware infecting the boot process, this error message can appear.
Cause 2: The TPM has been cleared or reset
BitLocker can optionally use a hardware encryption chip found on most modern PCs and laptops known as the TPM (Trusted Platform Module) to manage the secret keys used for the encryption of data. If this TPM is cleared or lost, either due to the user clearing the TPM manually in the BIOS/firmware setup or due to a TPM firmware upgrade as part of the system firmware/BIOS upgrade process, the keys the TPM contains may be cleared and the system will fail to boot.
Cause 3: BCD file is damaged
The BCD(Boot Configuration Data) file that contains boot configuration parameters for Windows system, is a very important part of booting process. If that file becomes damaged, then the boot process is halted.
