Unable to Install Windows 10 guest OS in Ubuntu 20.04 host using Virtualbox

I used to work with Windows 10 guest OS in Ubuntu host machines using Virtualbox. Recently I bought a ASUS Zenbook (UX325EA-EG701TS).
I installed Ubuntu 20.04.2 LTS on it and installed Virtualbox 6.1. I tried to install Windows 10 as guest OS, multiple times using different ISO files.
But every time it fails. Sometimes it fails during installation and some times during post installation, while configuring the keyboard etc.
I am not sure how to get the log messages so that I can identify the reason and possibly rectify it.
Any help is appreciated.
