Building a bootable USB for Windows with UEFI and NTFS

I found this procedure on the webs and used it slightly modified, as outlined below.

Become root with sudo su -
Insert the USB drive, and find its device name.

lsblk

sdk                 8:160  1  31.6G  0 disk
└─sdk1              8:161  1  13.7G  0 part /run/media/gill/OCTD

Unmount the partition.

umount /dev/sdk1

Run fdisk with the device name and remove existing partitions.

Workload Scheduler users: You need rlwrap

If you use the Linux shell very much, you find its history functions very useful. You can recall previous commands very easily, just using the arrow keys.
If you use the Workload Scheduler command-line interfaces, conman and composer, you really miss the history. Sure there's the redo command, but its editing capability is limited to the last command you typed.
