How to mount a non-system drive encrypted with truecrypt/veracrypt before logging into a Windows account?

Question

Encryption

Available: SSD with system and HDD with everything else. Windows user profiles moved to HDD.
I want to: encrypt the HDD completely using truecrypt / veracrypt. But the question arises, how to mount and decrypt the disk before entering the account?
Tried writing a script:

CD "C:\Program Files\VeraCrypt"
VeraCrypt.exe /volume \\?\Volume{b271efba-XXXX-XXXX-XXXX-000c2980f7d9}\ /letter D /q

And assign its execution through group policies:
- User configuration - conf. Windows - scripts - startup: works out and asks for a password, but AFTER entering the account for which a temporary profile is being created.
- Computer configuration - conf. Windows - scripts - autoload: I guess that's what I need, but nothing happens. Before login, I don't get prompted for a password.
I tried to slip the launch of the script into the task scheduler and a trigger to turn on the computer. Did not work.
How to get out?
