It is working perfectly. No errors and no downloading. Made one iso image

Slitaz

Puppy

Slax

System Rescue CD

Knoppix

Linux Mint


Again installed multicd.iso in USB by using unibootin (windows). Works

flawlessly except puppy which can be rectified by editing syslinux.cfg as

i mentioned earlier....
