I am attempting to perform a clean install of Windows 10 Education version on a new computer. The computer is a custom build and components are listed below. This computer is brand new and has no nor has ever had an operating system installed:


MSI MPG B550 Gaming Plus Motherboard (firmware updated to latest version)

AMD Ryzen 7 3700X CPU

32 GB DDR4 RAM (4 sticks 8GB each)

EVGA Geforce GTX 730 GPU

Corsair Force MP510 NVMe PCIe Gen3 x4 M.2 500 GB SSD


No other hardware is connected other than a USB keyborad. Ethernet is also disconnected. Computer does not have a DVD or CD drive.


I do not have access to a viable Windows PC. I have an employer provided laptop on which I do not have sufficient privileges to install Windows Media Creation Tool or Rufus. Also cannot access Diskpart from cmd.exe on this computer for obvious reasons. The only operating systems I have at my disposal for creating installation media is a Mid2012 MacBook Pro running Catalina or I could create a live Linux USB.


I have 3 USB sticks available to create installation media and have tried all three.

1. SanDisk Cruzer 16GB 2.0

2. PNY 16GB 2.0

3. Generic 8GB 2.0


So far I have tried the following methods for creating the bootable Windows 10 installation media from the ISO file I downloaded through my University's portal and MS website. (Win10_Edu_20H2_v2_English_x64.iso)


1.) Burn ISO image to USB using "dd" command in Apple terminal. This method does not work as the installer won't load when computer is booted from the USB.


2.) Format the USB using GPT and FAT32, mount the ISO, copy all files from the ISO to USB excluding install.wim (it is 5.2GB on this ISO), split the install.wim into two install.swm files no greater that 3.8GB, copy install.swm files to "sources" folder on USB.


3.) Same method as #2 except compressing install.wim to 3.9GB using


wimlib-imagex optimize <FILEPATH> --solid


My motherboard is configured to UEFI mode, Secure Boot disabled, AHCI, and UEFI USB Key as first boot priority.


I can get the installer to boot using methods 2 and 3 but the installation fails each time. Before I attempt to install I have tried launching command prompt and diskpart to clean the destination SSD so that the entire drive is unallocated space then restart before attempting install. I either get error "We could not create a new partition or locate and existing one", code 0xc0000005 or code 0x8007025D.


I have also tried creating a 10GB partition on the SSD formatted to GPT and NTFS and copying the install files from my USB to this partition, restarting, booting from the new 10GB SSD partition and attempting install. This method will actually start the installation process but fails after copying Windows files with a blue screen or "Windows could not prepare the computer to boot into next phase of installation.".


I have run chkdsk on both the SSD and all USBs and found no errors.


I have also tried all suggestions in the following links with no success:


Clean Install Windows 10


We couldn't create a new partition or locate an existing one.
