Description

Prepares a USB drive for use as an OSDeploy bootable device. The function:

• Prompts for selection of a completed BootImage from %ProgramData%\OSDeployCore\boot

• Prompts for the specific bootmedia folder (bootmedia or bootmedia_ca2023)

• Selects a suitable USB disk (7 GB–2 TB) via an interactive picker

• Clears, partitions (MBR), and formats the selected disk:

  • 4 GB FAT32 active boot partition (labeled with -BootLabel)

  • NTFS remaining-space data partition (labeled with -DataLabel)

• Copies the selected BootMedia to the FAT32 partition

This function clears and repartitions the selected USB disk. All existing data on the disk will be destroyed. Use Update-OSDeployBootUSB to refresh an existing OSDeploy USB without reformatting.
