I've been trying to install Ubuntu 20.04 on my laptop since its pre-release, every time when I downloaded the ISO file and try to install it in VirtualBox, it always gives this message:

The Error Message when trying to install Ubuntu Budgie

I've check the MD5 SUM of the ISO file, it is correct, so I thought maybe something wrong with the pre-release ISO? So I waited until the official release, I tried again, same result. Today I went out and perform a clean install on my another PC, it runs well and give me no issues.

PS: the screenshot is taken when I tried installing Ubuntu Budgie but the same error occurs as well in the Gnome version of Ubuntu.

But when I try to perform a clean install on my laptop, the same error message pops out again.

I am very sure that it is not the problem with the USB Drive/ISO file, I even ran a CHKDSK on Windows 10, and it reports that my hard disk has 0 errors.

UPDATE

I've found the issue here, this is because I have WSL2 enabled on Windows, for some reasons WSL2 and VMs cannot co-exist. After I disabled WSL2, the VM worked.

PS: WSL1 still works though, I think this is due to the fact that WSL2 is actually running as a VM.

See here for the full answer on how to disable Hyper-V: Error when installing Ubuntu 20.04 in VirtualBox. WSL2 uses Hyper-V components, which causes this issue.
