I understand that processing power was lacking but surely the os of yore must have had much smaller requirements. Also let’s assume we are booting up offline and no updates are indicated. What was Windows doing for 3 – 5 minutes that my android phone manages to zip through in 15 seconds?

Biggest thing is storage. The biggest part of booting up an OS is moving a ton of data into memory aka RAM all at once so that the OS can function properly. Phones and newer computers use flash aka solid state storage of some sort which exponentially faster than Tradition disk based storage so that massively speeds up boot times. On top of that ram is a lot faster than it used to be and so are CPUs. The amount of work that needs be done to boot an OS has not increased all that much in the grand scheme of things either so you can get much better boot times than were possible say just decade ago.
