[Bug 1051306] Re: Windows not found unless partition is mounted

[Colin Watson]

os-prober is very chatty in the syslog, and this may be more useful than
these (incomplete, I'm afraid) set -x dumps.  Could you perhaps extract
the syslog messages emitted by a run of os-prober?

** Summary changed:

- windows not found unless partion is mounted
+ Windows not found unless partition is mounted
