Another gremlin has been spotted in Windows 10’s Fall Creators Update, with this particular issue reportedly causing installation to fail for those with certain motherboard and storage combinations.

The problem is said to primarily affect those who use a motherboard with Intel’s X299 chipset and also have an NVMe SSD drive, as CNET reports (SATA solid-state drives are not running into trouble, apparently).
