Windows Server 2022 USB Installation from ISO

Open a PowerShell using the Run as Administrator option. You will need to change the path of the Windows Server 2022 ISO, and you will need to replace the disk number in the script before running the third command and make sure C:\Temp exists

# Define Path to the Windows Server 2022 ISO
$ISOFile = "C:\Temp\WindowsServer2022.iso"

# Create temp diectroy for new image
$newImageDir = New-Item -Path 'C:\Temp\newimage' -ItemType Directory

# Mount iso
$ISOMounted = Mount-DiskImage -ImagePath $ISOFile -StorageType ISO -PassThru

# Driver letter
$ISODriveLetter = ($ISOMounted | Get-Volume).DriveLetter

# Copy Files to temporary new image folder
Copy-Item -Path ($ISODriveLetter +":\*") -Destination C:\Temp\newimage -Recurse

# Split and copy install.wim (because of the filesize)
dism /Split-Image /ImageFile:C:\Temp\newimage\sources\install.wim /SWMFile:C:\Temp\newimage\sources\install.swm /FileSize:4096


# Get the USB Drive you want to use, copy the disk number
Get-Disk | Where BusType -eq "USB"

# Get the right USB Drive (You will need to change the number)
$USBDrive = Get-Disk | Where Number -eq 2

# Replace the Friendly Name to clean the USB Drive (THIS WILL REMOVE EVERYTHING)
$USBDrive | Clear-Disk -RemoveData -Confirm:$true -PassThru

# Convert Disk to GPT
$USBDrive | Set-Disk -PartitionStyle GPT

# Create partition primary and format to FAT32
$Volume = $USBDrive | New-Partition -Size 8GB -AssignDriveLetter | Format-Volume -FileSystem FAT32 -NewFileSystemLabel WS2022

# Copy Files to USB (Ignore install.wim)
Copy-Item -Path C:\Temp\newimage\* -Destination ($Volume.DriveLetter + ":\") -Recurse -Exclude install.wim

# Dismount ISO
Dismount-DiskImage -ImagePath $ISOFile
