From my experience, you should unpack the iso in the root directory of hda10. Use the kernels and initrd from the extracted iso. Remove the "from=/dev/hda10/linux/vector/VL6.0-Light-LIVE-Final.iso" from your menu.lst file. For the future, I have NEVER been able to run an live iso based on either Debian or Ubuntu. VectorLinux is Slackware based, so there should be no problem.
