With the drive connected, press F12 a few times at powerup. A menu will appear, among which will be the USB drive (as long as the system sees it as bootable).
@ejn63 And which option in BOOT in the Dell Bios should be selected to get the system to see the boot drive as present, then what should be done after it sees the drive: Start PXE over _____. I chose first choice as IPV6, then IPV4, then Windows system boot, but it keeps booting into the Windows login screen.
You don't need to alter the firmware setting. Press F12 a few times at powerup until the boot menu appears. If the system sees the UEFI bootable flash drive, it will appear in the list. Select it and boot from it.
If it does not appear, the system does not see it as bootable.
You've provided no information about the system model or the operating system on the flash drive and how it was prepared, so that's as much information as anyone can provide.
