    I have an older computer that doesn't have UEFI (Intel X58 chipset).
    I've installed Windows 7 and Windows 10 on it, from a thumb drive.
    I got a new hard drive and went to install the May 2019 update and it refuses to boot from the thumb drive.

    I used Windows 7 USB/DVD Download Tool and Rufus (MBR).
    Neither of them are booting.
    I tried putting Windows 7 on a thumb drive, using Windows 7 USB/DVD Download Tool and it worked.
    I tried putting Windows 10 on that same thumb drive, using the same Windows 7 USB/DVD Download Tool, and it doesn't boot.
    I downloaded the x32/x64 combo ISO using Media Creation Tool.

    Can you guys shed some light?
    Thanks...

    did you take a look at bios " legacy boot " option to activate ?
    when I bought my first laptop it was an uefi and when I re installed another os (seven) I was told to activate legacy boot in bios ( or something with legacy boot options).

    This motherboard doesn't have uefi.
    It's bios only.
    But, I did realize the problem.
    For some reason, it views thumb drives as hard drives instead of removable devices.
    As soon as I made that change, it booted right up.
    Now, I still don't know why the Windows 7 thumb drive booted and the Windows 10 one didn't.

    I have a Gigabyte GA-78LMT-USB3-R2 motherboard which uses DualBIOS (non-UEFI) chips and I can boot from the Win10 v1903 USB drive without problems.

    maybe use a different brand USB thumb drive like Sandisk as some brands work better than others
