Portable-VirtualBox does not run on USB drive

[park-changkyu]

Although the VirtualBox program itself runs on the USB, an error occurs when attempting to run the Guest OS.

Are there logs? I tried it under winpe, it works but only x64 on x64 system.
If you have a 64 bit system try creating an x64 file

the patch is not complete as far as you can see, on winpe when running x86 I got the same patch only with normal splashes.
If you have a 64-bit system, it is better to create it
