Hi there,
actually it's impossible to create Partition, Formatting and Multi operating systems utilities bootable disk in Windows without 3d software like
Acronis Disk Director.
This program has special tool "Create bootable media", so just click there and follow the prompts.
And you'll get the perfect bootable CD with copy, move, create, delete, resize, merge, restore partitions tools.
You could boot from it even when you can't boot to Windows.
Also if you have this partition manager software you could easily check the full hard disk size, and you needn't any dos command.
I highly recommend you to make a point of this option.
