Booting from USB
I had never had my computer set to boot from USB but I created a bootable flash drive with Win 10 on it and wanted to try it. I set the BIOS boot options to try the CD drive first, then USB, and then the Hard drive. It booted fine but I have a question now.
If I have a non-bootable USB storage device plugged in and either start up or restart my computer, after the BIOS post I get the message, "Missing Operating System" and the whole boot process stops and will not proceed to the Hard Drive. I had assumed it would work the same as the CD-ROM boot where if the media is not bootable, it just skips it and goes to the next option in the list. Now I have found that the same thing happens on my Win 7 machine. Is this normal? If it is, I will turn off USB boot again and just go back to burning disks.
