Mounting:

ntfs-3g[32246]: Mounted /dev/sda1 (Read-Write, label "", NTFS 3.1)

Mounted: 
macosx-prober: debug: /dev/sda1 is not an HFS+ partition: exiting
os-prober: debug: running /usr/lib/os-probes/mounted/20microsoft on mounted /dev/sda1
20microsoft: debug: /dev/sda1 is a FUSE partition
20microsoft: result: /dev/sda1:Windows 7 (loader):Windows:chain 
os-prober: debug: os detected by /usr/lib/os-probes/mounted/20microsoft
os-prober: debug: running /usr/lib/os-probes/50mounted-tests on /dev/sda3

Note that when the partition is not mounted, it says NTFS, and continues
the tests, so the error is there.
