Starting from a USB SSD or NVMe drive on the W10? It boots but then stops midway...
Two extra M.2 NVMe enclosures and one SSD USB with a clean 20H2 install boot successfully, but they all struggle initially before hanging. It seems there might be an issue I'm not seeing. Since the internal drives work fine, something is likely missing or misconfigured. My M.2 slot sits below my graphics card, making testing tricky. Would be great if I could just insert the W10 test drives and run them without hassle. Thanks for your help.
Windows doesn't allow external devices to boot. This capability existed briefly with Windows To Go, but it's no longer available.
There are ways to start from a USB drive, though it may require some time. https://www.techspot.com/article/1751-windows-to-go/ Rufus offers a feature called "Create Windows To Go USB Drive." Since you've previously installed Windows on an external SSD, it's worth testing that method again.
