Debian dual boot with Windows 7

[James Kramer]

Knoppix did not run properly on the system. The latest Ubuntu 10.04 64
bit seems to work well.

I am now working to repartition the hard drive.  Windows has a tool to
do this.  I first needed to defrag the disk.  I have a 1Tb  hard
drive.  After defrag by Window only 500Gb was available for a new
partition.  Windows stores a few sectors in the middle of the hard
drive.

I used Perfect Disk to defrag on the default settings and I was not
able to reduce the size of the defrag.  It did not remove the excluded
sectors in the middle of the disk.

I guess that I can use Gparted to repartition but I do not know what
data is stored in the middle of the partition.  Does anyone have any
suggestions?  I do not want to allocate 500Gb to a Windows partition.

Thanks in advance for the help.
