With the USB device attached, press F12 at powerup.  The system will show a boot menu. If the drive appears in the list, simply select it, press enter and the system will then boot from it. If you do not see the drive in the boot list, it's not UEFI-bootable -- you must use a UEFI-bootable device (i.e., not one that requires legacy/CSM support to boot, which your system does not offer).  Many Linux distributions are not UEFI-bootable in pre-built ISOs -- you may have to consult the documentation for your version to find one that is, or to prepare a bootable drive for use with this UEFI-only system.    
I am unable to find out the boot from USB option in my dell laptop bios setup.  I looked into the one-time boot menu and InsydeH20 Utility but can't find out the option for USB boot or a clue to switch to USB boot. Following are my device info:  Device model: Dell Inspirion 3505 BIOS version: 1.6.0 OS type: Fedora 36 (Workstation) Completely Linux based I am not getting a proper guide. Please help me out.
