GParted Live
Has PXE boot, USB stick and CD versions.
Boots up a Linux live environment and then you click the windows button (hah hah) system applications HDD erase.
There is also a partition manager in there that lets you format NTFS with offset. I have not played around with the advnaced features yet but I probably should. (Boot to CD, erase, partition NTFS with 32K cluster size for Vertex2 and then install...)
