This actually would be kind of handy.
I’m very much in the same situation that you are. My machine automatically reboots overnight so that when I login in the morning, it takes a few seconds to reload all of the startup software and just do a couple of things. It would be nice to know when it’s done.
Unfortunately, the concept of startup in Windows is incredibly complex.

What is startup?
When it come to the startup process, it’s hard to know when something is done. Some programs start and go away while others start, do something, and then keep running. Just because one program went away doesn’t mean that the program is done. A program that it handed off to might still be running.
There’s no way to really know when it’s technically done. There’s no way to really know what it means to be done.

Adding a sound to startup
If you take a look at the Windows Start menu underneath All Programs, there is an item called Startup. That’s a menu item that’s actually a folder that contains another set of menu items. If you put a shortcut in that folder, that shortcut will run at startup time.
Now, you could actually make a shortcut to an .mp3 file, a .wav file, or a program that actually plays an audio file for you, and then place that shortcut in the Startup folder.
One program that might be useful is a program called NirCmd. That’s a general purpose command line utility program that has an option to play an audio file. For example, in the Windows command prompt, you type NirCMD, mediaplay, a time, and then an mp3 file or a .wav file and it will just play it.

If you put a shortcut to that program or directly to the audio file in your startup menu, it will get played during startup.
The catch is that it won’t necessarily get played at the end of startup. But it will get played when Windows processes the startup menu items. It’s my understanding that those get processed relatively late in the startup process. So much of the startup processing will have happened before that audio file is played. It’s just not guaranteed that absolutely everything will be done when it is. But I think by the time it gets played most of the startup items will be done and you will probably be in a pretty reasonable situation then to begin using your machine.
But the ultimate answer to your question is no, I don’t believe there’s a way to do specifically what you’re asking. With the way Windows does startup, I don’t believe that there actually could be.
