Exactly what are you trying to do, and where?
Of more immediate concern is I see no System flag on any partition. This means the boot files aren't in proper order. They should be on C from what I can tell with part of the drive map obscurred by the strange error message. That error message may be anomalys if you're only trying to shrink a partition.
Did you replace the WIn7 boot manager with GRUB? This is not a good idea. Better to follow the course outlined here: Dual boot Ubuntu-Win7
