Hello. I am using grub4dos on a large USB drive that is formatted as NTFS. I am trying to boot BT4.iso, and it begins to load, however it seems to get stuck in an infinite loop, printing "NTFS Volume 3.1" over and over again. Here is the contents of my menu.lst:

title Backtrack4
find --set-root /ISO/bt4.iso
map /ISO/bt4.iso (hd32)
map --hook
root (hd32)
kernel /boot/vmlinuz BOOT=casper boot=casper nopersistent rw from=ISO/bt4.iso
initrd /boot/initrd800.gz
boot

The kernel is loaded and the boot sequence appears to be working just fine until the infinite loop starts. Does anyone know what I am doing wrong? I can provide more information if needed.

Thanks
