--- Comment #4 from Mark Millard <marklmi26-f...@yahoo.com> --- (In reply to Mark Millard from comment #3) I took a as-factory-shipped example of the type of USBC media (but 1TiByte instead of 2 TiByte) and tried to boot with the media attached (but no OS or such present on the media). No Synchronous Exception Eventually it booted to the internal Windows 11 Pro (despite UEFI having the internal media unchecked) So it appears that the Synchronous Exception that I've gotten on the original media is a response to something on/from that the media. Merely having non-boot media connected did not have a problem. -- You are receiving this mail because: You are the assignee for the bug.
