I see you have PATA drives - on a SATA drive you can only have 15 partitions
If libata is present it may have that limitation
And you are recommended not to have more than 12 logical partitions have I seen
Read the troubleshooter for the live CD (as valid for the dvd)http://www.linuxmint.com/wiki/index.php ... ur_Live_CD
There is a foolproof way to boot the live CD into recovery mode described there
Frankly I don't know what you should do, but the piix "trick" mentioned in the troubleshooter may help as it has to do with handling of disks
And - I don't find libata in my system - at least not as libata??
