I've just installed ubuntu 12.04. I didn't put my data yet, I want before to make sure that the installation is fine. And I get Disk Utility warning about misaligned partition.
sda2 is extended partition with
sda5 for swap and
/home. There is no other partition on the disc. From other questions about the same problem I've understood that I should boot my computer from live USB and fix the problem with gParted. The problem is that when I boot my computer from live USB stick and enter try mode, both primary partitions are mounted, so I can't do any operation on it.
Since I don't have any data yet, I can even re-install the system, but I should know how do set the installer to align the partitions in right way. I've chosen not to use the install option without partitioning, since I'd like to have
/home on separate partition. I could also try to fix it with the present installation, but I don't know how to unmount swap partition (and I'm not sure if it's reasonable).
Here is the output of
