I am not sure what would have caused it, but I suspect you are right. Maybe the clone didn’t work as well as I had thought, good enough for a single boot, but not for dual? I was just able to boot into Windows after seeing this response to another thread. I had tried the automated boot repair tool provided on the Windows install media, but following the Using BCDBoot to Manually Repair EFI Bootloader in Windows section of this linked resource worked. Now Grub seems to successfully point to my Windows boot config so I can leave Fedora as the main boot, but I am having to enter my Bitlocker recovery key each time I boot into Windows, but I’m pretty sure I ran across some other threads about that issue.
Thanks for the reply!
