Boot to USB

My laptop goes to black screen after the Dell logo. Support Assistant says there are no hardware issue. I suspect a Windows issue and created a bootable USB drive. However, all instructions I see say change the from UEFI to Legacy in order to set the laptop to boot to the USB, and that option is not available to me in BIOS. I see UEFI, I hot enter and no other option appears. Any thoughts/workarounds are welcome.

    While you should remove the service tag, that model (Inspiron 3573) is UEFI-only --  it has no legacy mode.

    It's impossible to be definitive without knowing the exact model (i.e., Inspiron 5553, etc.), but just about nothing made in the last 2-3 years has a legacy option any longer.

    If you don't see one, your system is UEFI-only and whatever USB you're trying to boot must be UEFI-bootable (FAT32 with a UEFI-bootable OS on it).

    With the UEFI bootable drive attached, press F12 a few times at powerup and choose the drive to boot from (you can't rely on just changing the boot order any longer, as you could with older legacy systems).
