Hi, I would like to disable swap on Wubi Lubuntu 12.10 during startup.

Turn off swap manually:
sudo swapoff -a
Turn on swap on Wubi Lubuntu:
sudo swapon /host/ubuntu/disks/swap.disk
gksudo leafpad /etc/fstab

# /etc/fstab: static file system information.
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/host/ubuntu/disks/root.disk /               ext4    loop,errors=remount-ro 0       1
/host/ubuntu/disks/swap.disk none            swap    loop,sw         0       0
What about /etc/sysctl.conf and "vm.swappiness=0"?

Any help is greatly appreciated!
