said by Camelot One:I would start by enabling boot logging, recording the results, then removing the card and repeating.
I have a boot log from before the card was installed and after. Strangely the "boot times" are within 20 seconds of each other despite the fact that with the card installed the "starting Windows" screen lasts over a minute. However, the "BootStartTime" and "BootEndTime" are the same without the card and with the card the end time is 2:16 after the start time. Why that difference is not reflected in the "boot time" entry is beyond me.
The only other difference I see is the item "BootIsRootCauseIdentified" which is "true" without the card and "false" with the card.
I have no idea what to make of this.
