Partition error?
Windows 10 Home, version 1903. I normally backup to an external usb hard drive using Macrium without any problem. Now I cannot anymore and get an error telling me 'partition 1' is invalid. I have no idea what partition 1 is or how it came to be created. I get the same error even if I do not include 'partition 1' in the backup. I am including relevant screenshots. Can I delete 'partition 1'? What should I do? Thank you.
