What do I need to share a partition for both Windows & Linux?
I wand to use a partition and to be accessible for Windows 7 & Linux Ubuntu for read/write operations. Can anyone recommend me something?
Ubuntu can read/write to NTFS partitions (which are the default Windows 7 type). So just create a new partition as NTFS with Windows 7, and then mount it with Ubuntu when you're using Ubuntu.
Details here.
Summary: use ntfs-config under Ubuntu.
Ubuntu Linux can read/write all the file systems Windows 7 can make, with the exception of exFAT.
