BLKID gives incomplete result

In the Boot-Repair log ( http://paste.ubuntu.com/1354254/ ) of this thread: http://askubuntu.com/questions/216627/problems-dualbooting-ubuntu-because-of-uefi/217035#217035 / http://ubuntuforums.org/showthread.php?t=2083639

We see that blkid outputs only this:

=================== blkid:
/dev/loop0: TYPE="squashfs"
/dev/sda7: UUID="322d3fa7-5d41-454b-993d-8e88fc569f54" TYPE="swap"
/dev/sdb1: LABEL="New Volume" UUID="3E8B-25CA" TYPE="vfat"

when parted/os-prober show many more partitions:

=================== os-prober:
/dev/sda3:Windows 7 (loader):Windows:chain
/dev/sda5:Windows Recovery Environment (loader):Windows1:chain
