VeraCrypt problem to decrypt hard drive

[spz93]

Hello,

I am contacting you to discuss my problem with VeraCrypt.

Configuration:

Dell Precision 7910
Windows 10 Pro (EFI)
256GB Hynix SSD drive
Encrypted with VeraCrypt 1.21

I had a corrupted Windows boot problem with the following error message:

The Boot Configuration Data is missing some required information: https://www.thewindowsclub.com/wp-content/uploads/2017/07/Boot-Configuration-Data-file-is-missing-some-required-information.png

To repair the boot, it was necessary to decipher the disk. I copied on a USB key files to start on the Rescue Disk (belonging to the machine) and decrypt the disk.

Once started on it, I selected the "Decrypt OS" option, typed the passphrase and the decryption started.

The next morning, the decryption completed, no error message, I restart, I still have the bootloader VeraCrypt, strange ...

I start with a bootable USB key of Windows 10 to repair the boot, the auto-repair fails, I pass in CLI, by typing the following commands:

bootrec /fixboot => Access denied
bootrec /rebuildbcd => The console finds 0 Windows installation.

With the DISKPART tool, the volume C is seen in RAW, Has VeraCrypt deciphered my disk? I pulled out the disk and connected to another machine, I try to open the volume, I get the following error message => Error: the process of encryption of the partition / drive has not been completed.

I'm stuck, thank you for helping me.

When I try to decrypt again from Rescue, I get the prompt "Decrypt?" again... (see attachment).
