[Solved] Windows 10 guest unbootable with XHCI enabled

[volvo_ks]

I've installed VBox V5.1.14 with Extension Pack enabled

When I try to boot into my Windows 10 (Build 1809) guest with XHCI selected, it is stuck in the booting screen, and the circle just loop for at least 20 mins before I perform a force shutdown
However, when I boot with EHCI and OHCI selected, it is perfectly normal and no problem can be observed
In the guest OS, Guest Additions has been installed, but the problem existed before the installation of that
In short, Windows 10 guest is unbootable when XHCI is on.

Thanks in advance

VBox V5.1.14 with Extension Pack enabled

That's an ancient version, we're now to version 6.0.4, try that...
If you want to go retro, at least try the latest, 5.2.26.

Thanks, that is solved
However I have to create a new machine and reinstall OS to work

OK, great, I'll mark it as [Solved].
But why you had to create a new VM and reinstall the guest? I don't get it...

It is kinda strange
After I update VBox, even booting with OHCI won't work
Reinstalling the guest OS with current VM faces BSOD so I decide creating a new VM which solve all the problem
The Win 10 ISO used is the same throughout the whole process, so I am also confused by this
