One of the Volumes Specified for Backup is Invalid

I got a message stating that “The backup failed. one of the volumes specified for backup is invalid because either not on a fixed drive, is not formatted NTFS, or is read-only. To convert the file system on a volume from FTA32 to NTFS, at an elevated command prompt type: CONVERT/FS:NTFS (0x8078011D)” when I try to create a system image in my windows 10 computer.

Backup Failed

Thus, I did this conversion that convert the volume from FAT32 to NTFS file system. After that I found my computer couldn’t boot up, it’s so frustrating.
