when i start x64 virtual machine then i plug iso of windows 10 64bit version 20h2 then virtual machine bug out into glitched rgb animation.

my device run official windows 10 version 20h2.

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

I wonder if this could be a reference to the transparency issue.

Could be possible, or maybe the green/yellow/black basket weave screen.

i tried to set paravirtualization interface to none but it did not help.

Paravirtualization should stay on 'Hyper-V', That's not the 'Hyper-V' that causes all the trouble. You aren't bothered by the troublesome Hyper-V.

Nothing else seems strange in the VM settings, except maybe too many processors. Try 2 for now.

This run of the VM boots from the CD-rom at 7 seconds, the boot screen toggles on and off once at 8 seconds, and is requested to turn off at 19 seconds. What happens between then? Can you post a screenshot?

The VM name "windows 10 insider preview" implies attempt to run insider preview Windows, which isn't technically supported. Can you download and try a regular Windows 10?

i tried putting regular windows 10 64bit iso version 20h2. but it does same thing. it start virtual machine but there is blinking cursor and rgb animation.

Images should be cropped and resized to get under the forum's 128kB size limit yet remain readable, then posted using the forum's Upload Attachment tab.

Please post a screenshot of this "rgb animation".

Cropping the image to just the 16.5% occupied by the VM window would have been preferable to a low quality JPEG covering your entire desktop. Click the Start button and type "Snipping Tool" for a built in tool in Win10 that allows you to capture any rectangle on the screen.

However - yes, we have seen that pattern before - though for the moment I'm having troubling finding search terms that produce any of those discussions. One thing you should definitely do is update to the latest version (6.1.18), to see if the problem even still exists.

One other thought occurs: the window size does not seem to correspond to the display size selected in the log. If you are dragging the window border to resize it then stop doing that until Windows 10 is installed. For the moment you are only booting from the installer CD, you do not have an OS yet that can cope with display changes.
