Windows (10) To Go on a USB 3.0 HDD not booting.

I've been trying to boot the Windows 10 Technical Preview (WTG) from a USB 3 attached hard drive with no success.

My BIOS complies when I tell it to boot from the USB device, also, Windows starts to boot, and from the LED on my HDD I can tell that it is running at USB 3 speeds, but after a couple seconds the HDD just stops and the boot process is interrupted with the message "INACCESSIBLE_BOOT_DRIVE" (or something like that, the main issue is the same).

The weird thing here is that I can boot Ubuntu from the same device and port without any issue and the Windows installation boots fine on a USB 2 port, I haven't tried to use a USB 2 cable on the USB 3 port yet, since I don't have any available right now, but I suspect that it'll boot.

To me it sounds like a driver issue, thing is, when I boot into the installation in question via a USB 2 port, the driver for the USB 3 host controller is loaded and working fine (tested with USB 2 devices, since the only USB 3 device I have so far is this HDD). Maybe it is not being loaded on boot? if so, is there any way to make it do so?

Thank you in advance.
