System Encryption Pretest failure - Reboot loop (Win 10 Pro - Gigabyte Motherboard)

[Shimmering Daydreams]

Motherboard: Gigabyte Z170-HD3P

BIOS: American Megatrends (version F22g)
OS: Windows 10 Pro x64 (yeah, yeah, it's only temporary, calm down)

The issue:

After setting things up for a system encryption I am prompted to complete the pretest.
However, after restarting, the Gigabyte and Ultra Durable logos come up, with the BIOS key configuration info on the bottom, and then the system just dies. it boots down, and then reboots again, only to shut down again. And this would continue if I wouldn't interrupt the boot sequence. So basically, it boots up until the BIOS logo, but then it shuts down.

I've tried it again and again with different BIOS settings, but it's always the same end result - restart loop.
I can see the VeraCrypt bootloader. It's just that whenever I use it, the computer shuts down.

I don't think this is the issue, but as a side question: Is it a problem, that I store my Documents, Desktop etc files on a separate HDD, and not on the system drive? I assume it isn't. Perhaps it would cause problems if I would only encrypt that HDD.

I hope someone has a solution. I tried my best at resolving this issue.

Hi,

I have the same issue on a Gigabyte GA-Z170X-Gaming 7 (version F22i) motherboard, Windows 10 Pro x64 (version 1909 , fresh and clean install) and with 1.24-Update4.
I would like to encrypt my system disk but at the pretest the PC just keeps rebooting and rebooting. I can select the VeraCrypt bootloader manually from the boot devices but it always got into the same, endless rebooting loop.
I have to use the recovery usb drive to start the operating system selecting 'Boot Original Windows Loader'. For fixing the original booting process I have to ask VeraCrypt to uninstall the pre-boot authentication component.

Is there a solution to this problem?
