Hello,
There is no '/boot' volume in the source information returned by sysinfo. Besides it reports: Error: Can't have a partition outside the disk!
OTOH df has returned '/dev/sda1' as '/boot'. Is it possible it is actually on '/dev/sda'? If that's the case - bad luck, Converter can't work with unpartitioned disks. If not - please post the 'fstab', too.
Regards,
