Step 1) Disable legacy protection if it has by entering your own password in BIOS, then disable legacy protection.
Step 2) Choice your way to fix this because there is 2 ways to fix this: Install Windows To Go on Flash drive and boot it from PC\Laptop second way is use two flash drives one where is installation second flash drive is need to use for place OS like Windows 10,8,7,Vista,XP Linux, iOS etc.
Step 3) If you choose version Windows To Go you need only one flash where to install it before it you need to get Software called Rufus at site: https://rufus.akeo.ie/downloads/rufus-2...., after download it run and it will show drive to install choose your and select disc icon after that browse your selected ISO installation if it has Windows To Go Rufus will automatically show this option if it has, like almost all ISO downloaded from Microsoft, msdsn.microsoft.com etc. it will take long hours but you will get OS installation on any Flash drive where is enough free space, reboot PC\laptop make sure USB flash drive is in first BOOT UP place set by BIOS. All OS is on your flash without any BOOT option straight by Rufus
Step 4) If you choose version 2 flash drive version you need 1 flash with OS installation files like Windows 7 and 1 flash drive where to install it, you can use similar software Rufus to write in flash OS installation without checking Windows To Go version in Rufus this is fastest way to install OS.
