If windows 10 still works when you go to reinstall, you can go to advanced startup and use the Use a device menu to boot from a USB without needing to go into BIOS.
go to settings/update & security/recovery
under advanced startup, click restart now
this loads a blue menu
Choose Use a device
put USB into PC and/or pick it from the list.
PC will restart and run installer
Otherwise, its likely you would need to turn secure boot off as it stops PC from booting from USB, it only allows secure operating systems to boot.
