Hello,

I am trying to boot Memtest86+ from USB ISO and it is just saying "Unable to Boot: Missing Operating System".

Can anyone give me any advice?

I'm afraid that tells me nothing as I have no idea what instructions you were following.

Anyway. Either you made a mistake in following the instructions to create a bootable USB drive or you haven't configured the BIOS of your computer to boot from a USB device.

I downloaded Memtest86+, ran the application, followed the .exe, checked "Format Drive", and burned the ISO to my USB. Inserted USB into PC, selected to boot from the USB, and instead of running Memtest86+ I got that message.
