VirtualBox error - VM boots, but Windows 10 won't start

Question

I'm trying to run Windows 10 using VirtualBox on a Debian 9 machine. When trying to set up the VM, I couldn't choose the 64-bit version of Windows 10 in the menu, so I downloaded the 32-bit ISO instead. When trying to start the VM, I get the following error message:

What's the problem? Are there any good (and free) alternatives to VirtualBox that could do the job? I need to do this on a workplace machine on which I can do sudo, but have no root permissions (and this will most likely not change in the future).

UPDATE: I followed the instructions here to check if VT-x is enabled and it seems to be disabled (the register returns 1 instead of 5), but unfortunately I cannot do anything about this at the moment. However, after following Ramhound's links and the advice here to reduce the allocated RAM to below 3 GB, I got this prompt:

I'm neither using OS/2 nor QNX - so when I click Continue, the VM actually seems to start and I even get the proper Windows startup screen:

It didn't progress from here until I finally switched off PAE/NX, and now I'm getting this Windows 10 bluescreen:

Which is kind of strange, because the CPU (Intel Core i5-6500) supports PAE, so it should not be necessary (or even counter-productive) to disable PAE/NX, right?

Imho the VM is already up and running and it's just some VirtualBox setting(s) causing the hiccup. I feel like being this close to the solution... Here is the complete VirtualBox logfile, maybe this contains some clues?

UPDATE: As Didier suggested, I also tried a ready-made Windows 10 VM as explained here. After downloading the VM from the Microsoft Dev Center and fixing a minor error/incompatibility (in 2020, absolutely nothing seems to work out of the box anymore), I tried to start the VM. Result:

Answer 1

There are several possible causes for the error, see this.

As per your description, check in your BIOS if VT-x is available and enabled.

See also this. Check if it is a RAM related issue (allocate less than 3Gb). Check if turning PAE/NX on/off works (Virtual Box "Settings" > System Settings > Processor > Enable the PAE/NX option). Check if also enabling VT-d at the BIOS level works.
