Validated that the portion had renamed according to the Winclone Image and file format (no NTFS after restore from image)
After restoring, it wasn’t NTFS? That is strange.
Error “Unable to verify startup disk” my only option is to select a different startup disk, I select the Mac OS portion and boots back into MacOS.
Is the error in Windows or in macOS startup recovery? If it is macOS startup recovery, this means you need disable secure boot for Windows.
Assuming you have a “new” MacBook with a T2 Security chip, you need to boot into Recovery mode (CMD-R) and DISABLE the Security features. I had completed my install and had things working, but after re-enabling security, the Mac refused to recognize the “external” device (even though it was in fact a partition ON the main SSD). I don’t know if this is a Mac thing, or that it simply does not like seeing “unsigned” operating systems at all. But after re-DISabling the security boot features, I restarted and have been working just fine for the past weeks.
