Create boot media

From GNU/Linux you can use dd tool (⚠️ Set the correct USB device. Use fdisk -l. Here with /dev/sde USB device.) :

root@host:~# dd if=debian-10.5.0-amd64-netinst.iso of=/dev/sde bs=8M

Under Windows, you can use UNetbootin: https://unetbootin.github.io/, yumi: https://www.pendrivelinux.com/ or Rufus: https://rufus.ie/ tools.

Or even simpler: burn a cd

See your manufacturer's boot options. For example, for Dell workstations, press F12 during startup.
