Comment 3 for bug 930676

The boot part isn't an error; that's expected on EFI. I suspect it's unrelated.

In syslog, we have:

And earlier in the log:

Feb 11 18:18:49 ubuntu kernel: [ 4.607400] sda4: <bsd:bad subpartition - ignored
Feb 11 18:18:49 ubuntu kernel: [ 4.607402] bad subpartition - ignored

Feb 11 18:18:49 ubuntu kernel: [ 4.607413] >

So the system is definitely badly confused about what sda4 is; but what I'm not sure from this log is which partitions you selected to import things from - Windows or Linux? If you could supply that information then that would be helpful.

Evan, one thing that definitely should be fixed is a syntax error on line 32 of ma-ask, which has been there since natty:

- if [ "$target" = "$location" ] || "$home" = "$location" ]; then
+ if [ "$target" = "$location" ] || [ "$home" = "$location" ]; then

I'm not convinced that that's the sole cause of this bug, though. I'm at least going to reassign this over to migration-assistant since that's probably closer to the cause than ubiquity is.
