so you can’t boot windows from the bios? In that case I think you have to reinstall windows.

try going into root and running grub-update. also, do not run it like: “$ sudo grub-update”, but as “$ su” and then “$ grub-update” that might fix the problem. also ensure you can boot into windows from bios.

the main reason are package managers, since the package managers on linux are much easier to use than winget(the one in windows). apart from that, there are not many other reasons to switch.
