I now have the issue that my boot ssd reports poor health in SMART and I need to clone it to a new one using Macrium reflect but after doing that the new one is not bootable, complaining that it is missing winload file, even though it has a complete copy of all the partitions and files from the original boot drive.
I tried the bcdboot copy command on the new drive while booted on the old one and it always says
Failure when attempting to copy boot files.
