using UBCD on a USB stick has become a non-event with v5 (at least for me).
won't boot, sometimes gets to a black screen with a flashing cursor at the top left..

todays excitement is to try this persons "fix"

i took me like a week to figure it out but its the easliy way i did it and it worked. i downloaded the UBCD and made it into an iso. then i downloaded super grub iso cd. then i downloaded ultra iso opened both files with it.copied the super grub to my desktop then i opened the ubcd iso with ultra iso.then i delete the folder that said syslinux and replaced it with the ones from the super grub iso. when to bootable tab in ultra iso then when to write bootable disk.plugged the usb in then let everthing copy and it worked. :-)
