Is the disk an MBR or a GPT disk? If the disk is a GPT disk, please convert it to MBR disk and try again.

Please convert the external hard disk to MBR partition scheme and create two or more patitions (one small FAT32 partition for the system partition, one NTFS partition for the boot partition, and other partitions for data partition), then use WinToUSB to create Windows To Go following the guide below:
http://www.easyuefi.com/wintousb/faq/en_US/How-to-use-WinToUSB.html

The best partition layout is as follow:
Partition 1 FAT32 500M System partition
Partition 2 NTFS ...G Boot partition
Partition 3 ... ...G Other partition
... Other partition

In particular, both the system partition and boot partition must be primary partition, and we recommend using built-in Windows Disk Management to partition and format the disk. This type of Windows To Go drive can boot both BIOS-based and UEFI-based computers.

After the creation is complete, please make sure that you change the BIOS to boot from USB drive.
