Linux installs like Ubuntu take about 20 minutes.
The last time I installed windows 11 (thank God only once) it took me a total of 7 hours divided over 3 days. It was hell, requiring multiple iso downloads, multiple tries to burn a USB with a variety of tools, loads of searching and reading documentation, multiple BIOS settings and a BIOS update, multiple install attempts, searching, downloading and installing drivers, then finally on the winning install it still took like an hour with god knows how many “fuck off and do your job” clicks.
Mind you, this was on the same machine where right before I installed Linux on a separate M2 device
Windows installations are a horror show.
