In my experience, installing Windows 11 on a HDD typically takes no more than an hour.
I suspect the issue may lie with either the installation media you're using or a problem with the hard drive itself.
- How did you create the installation media you're using? Did you use Microsoft's official Media Creation Tool, or did you opt for a third-party utility?
- If it was a third-party tool, which one did you use?
I await your reply.
