Multi-bootable USB

Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

The list of bootable images i'm trying to create are

1. Windows 10 (A full OS running from thumb drive)
2. Windows 10 ISO (Bootable disk image for fresh install)
3. MemTest86+

Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!

How to fix no bootable device?

I’ve been trying to fix my laptop for a while now, it either brings me to a screen with a blue box saying no bootable device or a black screen that says no bootable device found, I’ve turned on legacy mode and everything and i’ve entered the numbers into the keyboard after turning on legacy mode and it just brings me to the same black screen that says no bootable device, is there any way I could fix this?
