Looking for a simple program that I can boot onto from a cd rom to Zero Fill my hard drive.

Used to do this back in the day with floppy's but lost the program and new computer doesn't have a floppy drive.

The manufacturers web site should have the diagnostic utilities
for download on thier website.
These uasually include write zeros to the drive.

Presumably, you are trying to wipe the drive before you either sell it or get rid of it?

Regardless, see Elvandil's list here

Boot up any Linux Live CD (Knoppix recommended, also Ubuntu), and run the shred command:
$ sudo shred -n 2 -z -v /dev/hda1

where -n 2 indicates two passes for writing random data
-z indicates finish the wipe by overwriting the drive with zeros
-v shows your shred's progress
and /dev/hda1 indicates the partition to be shredded.

If you don't know the partition to be shredded, just run the command:
$ sudo fdisk -l
and look for an indication of NTFS for your Windows hard drive in the /dev/hdxx terminology.

Use the menu pull-downs to open up a command line window aka Terminal in which to execute the above commands.

You can download and burn the Linux Live CDs (ISO images) from here.
