I'm having trouble with my laptop since the display is damaged, and I can't see about 20% of the middle screen. I was going to reboot Windows but I can't see some important installation prompts due to the broken part. If I borrow an external monitor and connect it to my laptop, will the monitor display the Windows installation process?

It's a bit hit or miss. The easiest way to find out if it works is to just hook up the monitor and power on the laptop. If it doesn't show up, then you'll need to explore other options.
It really depends on your laptop model. Some laptops will show the display on both the external monitor and the internal screen, but others might need you to disconnect the internal display to force it to use just the external one. It's a bit of a mixed bag, so you might want to check the model specifics if you can.
Usually, when you connect an external monitor, Windows will automatically mirror the display. So if you're starting a fresh install and have the monitor plugged in, it should generally show something on the external screen after you boot up.
