I am trying to start up my OS in virtualbox. In this step I just want to make sure that the EFI bootloader can start up. The code I use is from the UEFI bare bones tutorial, but is compiled under MSVC using this repo: https://github.com/pbatard/uefi-simple as a starting point. It gives me a normal boot.efi file. In order to get the vdi, I followed the instructions on the UEFI page using WSL, then converted the .img to a .vdi using VBoxManage. My .img and .vdi has one partition, the EFI System partition and then about 8.5 gb ntfs Microsoft basic data. In the EFI system partition I have the 64-bit bootloader in boot/bootx64.efi (renamed from boot.efi) and it also the same file renamed as main.efi in the root directory so that I could try starting it if the boot fails. However, whenever I start the VM, it goes to the virtualbox startup screen, then straight to the black screen and blinking cursor. I have tried going to the boot options(F12), but that still takes me to the black screen and flashing cursor. An image is attached, unfortunately the cursor has gone but it is in the top left corner.
Here is what I see:
- The black screen

In terms of what I have done for this, I have disabled the Windows Virtual machine feature and Hyper-V and remade the VM. VT-X is enabled on my system. In all fairness, I have found near-to-nothing in terms of what to do on this issue, and when it happens with a unknown OS there is simply nothing on the matter.
Here are the logs:

I would please like to know what the problem here is, and what I could do to solve it and get my OS printing "Hello world". Apologies for the inconvenience, but thanks in advance.
Thank you for your time,
