After reading this, write down (on paper!) all partitions you need:  type (ext2, ext4...), size in MB, destination (/ - Root, SWAP, /home, etc) and the name (mountpoint, like /home or /mydata), like in the fdisk output (/dev/sda1, /dev/sda2, etc.).
From this output, I can deduce that you have a 1 TB drive.
This translates into this:
1,000,000,000,000 bytes / 1024 = 976,562,500 KB;
976,562,500 KB / 1024 = 953,674.31 MB. <--- This is the value you need to use when partitioning
This translates into 931,32 GB and 0.909 TB.

You also need to create a NTFS partition in order to be able to install and run Windows alongside Linux.

I think the disk is 500GB, not 1TB.  The fdisk numbers add up to 465.7 GB which would reflect the original post which says 500GB.
