Thak you for all the help:
I was unable to make boot-able USB drive, in-spite of fact my net book accept booting from USB. However i was able to burn a ISO dick, DM5SUM. using Nero Free graphical DM5SUM ( very easy) then only able to burn by ISO burner. all other methods gave me a toast. I then dual booted using Grub2,which is part of peppermint ice distro, by manually formating D:, as ext4. using small USB for Linux-swap.
Even though i was not successful in my original quest. for now i consider my problem solved. This may be simple solution for all New-bie like me.
