Need help installing Windows 10 on DeskMini A300

So I've been having some problems trying to install Windows 10 on this machine which I just built.
* Installation Attempt
- Official Windows 10 ISO downloaded from https://www.microsoft.com/en-gb/software-download/windows10ISO,
May 2019 update, English, 64 bit.
- RYZEN 5 3400G
- 2x4GB RAM 3200Mhz RAM (showing as 2933Mhz in the BIOS as expected)
- BIOS updated from 3.4 to 3.5
- Default BIOS settings so; UEFI mode, CSM disabled, fast boot disabled etc.....
- Single SATA hard drive connected to port SATA-1
- USB mouse, USB keyboard and WiFi module connected
- Created FAT32 bootable USB drive via Terminal on MacOSX as documented here: https://www.top-password.com/blog/create-windows-10-bootable-usb-from-iso-on-mac/

So with the above setup the USB drive boots correctly and I'm able to start the installation process.......however after selecting the disk partition (unallocated, which means the installer will create the necessary partitions) to install windows it attempts to begin the first step (copying files.....0%) but immediately gives the error message:-
"windows could not prepare the computer to boot into the next phase of installation"

* Troubleshooting Attempt with NO success
- Use different USB pen drive to create the Windows Boot
- Tried UNETBOOTIN to create the boot drive instead of Terminal
- Bought new SATA drive, old one was a mechanical and new one is SSD
- Disconnected Wifi module
- Disconnected USB keyboard
- Downloaded older Windows 10 ISO, Oct 2018 update, English, 64 bit, however funny thing is this previous update does not allow you to create a bootable FAT32 USB (at least not directly) because I get the following error message when I try: "The file "install.wim" is too large for the destination file system".

So what should I try next? Please help.........
* Try legacy mode for install (CSM enabled)?? (which seems inferior to UEFI since I might want to dual boot linux later on)
* Try an NTFS USB?? (I've read this won't work for UEFI install)
* Get a friend to help create the boot USB from a windows machine using RUFUS?? (thats annoying)

Thanks

Hi,
I just encountered the same issue.
On my end, I have similar specs except for 1x16GB RAM 3000Mhz and 1xM.2 480GB NVME SSD
I have the exact message from the windows install.

Did you find a way to install Windows10 after all?

Thanks

I recently bought a DeskMini A300 and I had the same problem. The spec in my sig is for my older ITX build so here's the spec for my new Desk Mini:

- Ryzen 5 3400G.
- Two 8 GB HyperX Impact DDR4-2933 SODIMMs (on QVL).
- Crucial CT500P1SSD8 500 GB MVMe SSD installed in the socket on the underside of the board.
- UEFI/BIOS P3.50, as supplied - the box has the Ryzen 3000 compatible sticker.

I have the USB 2.0 socket kit, which provides a pair of USB 2.0 sockets on the side of the DeskMini case. Since I was installing Windows 10 (1903, freshly downloaded and built using the Media Creation Tool) from a USB 2.0 thumb drive I plugged it into one of those sockets. This turned out to be a mistake because with the UEFI set to defaults the USB drive booted to a pale blue screen with no test at all, and after a minute or so the system automatically powered down. I found that moving the thumb drive to the USB 3.1 Gen 1 Type A socket on the front on the DeskMini fixed the problem. The USB 2.0 sockets on the side of the case are fine for plugging in a mouse and keyboard, and I was able to boot a Linux Mint 19.2 Cinnamon installer thumb drive in either of them, just not Windows 10.

Recommend a program that can make a boot disk without downloading iso files.

Just download and install this tool on working computer,then lauch it and follow its instructions to create a Windows bootable disk.

Hello! I have Windows Server 2016 installed on DeskMini A300. Where I can get driver for Windows 2016?
