This how you can mount windows partitions in ubuntu. You can only read NTFS but you can read and write on FAT32.

1. Run this command to see what partitions are NTFS/FAT32: sudo fdisk -l
you will get something like: /dev/hda1 ... HPFS/NTFS

2. Create a new directory to mount the partition to: sudo mkdir /mnt/windows

2. Backup fstab (which is the file to configure partitions): sudo cp /etc/fstab /etc/fstab_backup

3. Run this command to edit fstab using gedit (you can use any editor) : gksudo gedit /etc/fstab

4. Copy this line to the end of the file and change hda1 with the correct windows partition from step 1:
For NTFS: /dev/hda1 /media/windows ntfs nls=utf8,umask=0222 0 0
For FAT32: /dev/hda1 /media/windows vfat iocharset=utf8,umask=000 0 0

done!

The next time you restart ubuntu, it will mount automatically.
