Creating a Bootable Windows 10 USB Drive on Linux

I ran into this problem recently, and it took me a while to solve it because I couldn’t find very good material online. I hope this post helps some people reduce their frustrations.



  1. Plug the drive in. We’ll assume that it comes up as /dev/sdX.
  2. Destroy the old partition table. # dd if=/dev/zero of=/dev/sdX bs=512 count=1 conv=notrunc
  3. Partition the disk. # echo -e "n\np\n1\n\n\nt 1\n7\nw\n" | fdisk /dev/sdX
  4. Create the NTFS file system. # mkfs.ntfs -f /dev/sdX1
  5. Create mounting directories. # mkdir -p /mnt/usb /mnt/iso}
  6. Mount the installation ISO. # mount -o loop winstall.iso /mnt/iso
  7. Mount the USB drive. # mount /dev/sdX1 /mnt/usb
  8. Copy over files (-a for archive mode, -v for verbose). # cp -av /mnt/iso/* /mnt/usb/
  9. Unmount everything. # umount /mnt/usb /mnt/iso
  10. This is where it gets a bit strange. Windows uses the disk MBR to load the partition EBR for boot, so we must prepare both.
  11. Prepare the partition EBR. # ms-sys -n /dev/sdX1
  12. Prepare the disk MBR. # ms-sys -7 /dev/sdX
  13. Wait for the buffer cache to flush. # sync
  14. Reboot into the USB drive.


The installer won’t proceed after I select a disk with the error “we couldn’t create a new partition or locate an existing one”. I had to unplug my primary Linux HDD’s SATA cable so that the Windows drive was the only one.
