    Hi, I have a bootcamp partition on an external usb flashdrive. Is it possible to plug the mac to an external monitor (lets say Dell's U2515H), then plug the flashdrive to one of the monitors USB 3.0 and boot from there?

    Thanks!

    I am 99% sure that USB bus from any monitor's hub is working after the monitor's/GPU driver is loaded (inside OS/Windows environment) and it's not loaded during boot.

    I may be wrong also...

    Unlikely, it's possible, in theory, with a USB hub built in to a monitor connected by thunderbolt, but as the poster above points out this has many possible points that may cause a problem. Give it a try and let us know.

    Checked out the linked monitor it only connects as a monitor there is no way to get data from the monitor to your computer so it certainly won't work with that monitor (nice though it is).

    It looks like it uses a separate USB cable (similar to my U2410s), so if you connect that to the Mac you should be good to go.

    You can -try- to boot from the monitor's USB3 port.
    But my -guess- is going to be that it won't boot that way.

    Try this:
    a. Plug bootable flash drive into monitor's USB port
    b. Press power-on button
    c. Immediately hold down option key and keep holding it down until the startup manager appears
    d. Do you see an icon for the bootable flashdrive?
    e. If so, try selecting it with the pointer and hit return.
    f. What happens now?

    It uses a separate USB cable to connect the built in usb hub to the computer.
