I had a lot of issues when installing Debian after some days, because of a non-optimal suggested partitioning layout, misconfigured mirror-server list or network for example.
For what’s worth I never had those kinds of issues with the Debian installer, to me it seems that anyone capable of installing Windows 10/11 is capable of installing Debian on the bases of “next > next > next” everything as defaults and will get to a working desktop.
I’ve seen a few people complaining about the Debian installer but I never had issues at all. From servers to laptops always seems to get things right for me.
