Hi Wepee ,

Thank you for reaching out to the community, Please refer the following - Reimage Sophos Firewall - Sophos Firewall
Additionally, ref: Cloud, virtual, and software appliances - Sophos Firewall

Did you try installing the XG software as an application in windows or as a stand alone device

stand alone device

Please try changing the BIOS to legacy mode.

Yes, my bios is in CMS mode. 
If I did not set to this mode, SFOS won't install on my PC at all, because it does NOT currently supports in UEFI mode.
The problem is I have already installed the 2nd time. Answered all the set up questions.
And this weird problem comes up.

Vivek Jagad I reimaged my usb drive and run the installer again, but still won't work.

BalenaEther will complain it is a compressed image, and it won't proceed in flashing the ISO file to my USB thumb drive.

So I have been using rufus, and always use dd image mode to write ISO into the thumb drive.
