NOTE: Recent releases of Windows 10 contain a file (install.wim) larger than 4GBs requiring it to either be split to accommodate the 4GB maximum file size limitation of FAT32 or the drive to be formatted as exFAT. Read carefully and download/install any required resources before attempting these procedures.ĭownload the Windows 10 ISO file and have an 8GB or larger USB flash drive ready. This procedure is intended as a replacement for ' How to create a bootable Windows 10 USB in OS X using Terminal' as the technique described there is relevant to Linux hybrid ISO files (see references) but is unlikely to produce bootable Windows media. Windows 10 is described here but these instructions are valid for Windows 7/8. It can optionally be made BIOS bootable for legacy systems/installations as detailed below if desired. The resulting media will be bootable on any UEFI capable system which should be sufficient for the vast majority of computers in use today.
This guide will detail the procedure to create a bootable Windows installer on a USB flash drive from either platform.
