@Sebastian-Roth Ok so I found a fix for single boot. By a chance several of the devices worked after a complete reimage and have no issues. The other devices that still had issues had a slightly more strenuous issue.
Install Iso Image Via USB:
Windows 11 and Windows 10 (Version 1709 and newer):
Rebuild the BCD store.
First run the command below to back up the old BCD:
ren BCD BCD.bak
Now re-create it using this command:
bcdboot c:\Windows /s <boot letter>: /f ALL (You can add a switch before /s for the computer locale: /l <language code>. By default, /l en-us English USA is used.)
bootrec /rebuildbcd
