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
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. Fortunately, I used WinPE and DiskPart to reformat the volume to FAT32, and then use the bcdboot to copy the boot files to it, then the computer can boot again.
I just confused about this problem? Can anyone give me some advices? Thank you in advance.
