It seems the partition table is getting corrupted, possibly by an incorrect offset being used.
I would like you to dump the MBR created by both windows and Ubuntu.

First in windows create an MBR structure with the partitions as you just have then boot into Ubuntu.
When in Ubuntu run the following command to dump the MBR:
sudo dd if=/dev/mapper/pdc_cdgjdcefic of=winmbr.img bs=512 count=1

Then open up gparted and create a new partition structure (msdos), setup the same partitions and run this command:
sudo dd if=/dev/mapper/pdc_cdgjdcefic of=linmbr.img bs=512 count=1

This will leave you with two MBRs dumped in the form of .img files.
Could you please tar (archive) these and upload them for me to analyse.

Thanks.
