Reinstalling Windows 8.1

[Philtor]

Just wondering about something. I'm aware you install using a place holder key and then enter your key after having installed Windows. In the event there is no key sticker on the machine then I understand it's stored in the BIOS. In this case how does one install? Do you still need to use a place holder key or what?

Thanks!

So even if the key is stored in the BIOS it must be retrieved prior to a reinstall? I can see this being an issue on a non booting machine with no license key sticker mind.

Thanks for clarifying chaps.
