SGI Indy bootup may sound cool but probably annoying after the first few times you hear it: https://www.youtube.com/watch?v=CH9saUP2460
Another I find cool is this one from apple: https://youtu.be/d8szceStqZI?t=37
- "The function of this sound is to tell the user that the hardware is running like it is supposed to, and that the disc has successfully been read. To add, the swooshing reverse sound is designed so that it can go into loop if the disc couldn’t be read, and we can understand if something went wrong."
- "I thought of the structure, selected the tones, and gathered the instruments in 2 weeks, and the studio work was done essentially in 2 days. I kept thinking from the start that I wanted the sound image to be something exciting, like that feeling when you walk into a cinema. I really wanted to communicate and reinforce that something fun is going to happen."

The Windows sound doesn't play until after a very long, grinding boot sequence with an ambiguous moment of completion, so its slow, grand crescendo is a fitting indicator that the show has now begun. The Mac sound by contrast is played the instant you push the power button, and correspondingly it has a satisfyingly immediate beginning; its single richly textured chord seems to want to convey that pushing that button was the correct decision, and your day can only get better now that your Mac(tm) is powered up.

Most the game consoles have a nice startup... an arrangement of all of them is nice too https://www.youtube.com/watch?v=mLq_P0K4jvA
In addition, Windows XP and Windows 7 were the two most familiar Operating Systems that I used, and their startups probably are the most pleasing to my ears. [1][2]

It reminds me of my good ("old") days on the computer.
