You need to burn those .iso back to cd as data. In easy CD choose 'Record disc from image' In Nero select Disc Image or Saved Project. You should then be able to boot of the first cd/dvd and begin the install process.
I don't think it is possible to boot directly from an ISO (since this is no hardware). What you can do is to boot from any kind of hardware (CD/HDD/USB) and tell the bootloader where to find the rest of your OS. And this may be an ISO.
this is for computers capable to boot from usb but for the others? it is posible to boot the kernel from a floppy and then ... here is the place where I do-n know what to do!
OK, you have to be able to boot from something! You asked for USB, I gave you USB. If you knew that you cannot boot from USB, why did you ask for it?
Yes, you can also boot from floppy, if your computer has a floppy drive and the BIOS is able to boot from it
For example SUSE (my favourite distro): download floppy images for the version you would like to install. They are in the folder /boot on the SUSE server or installation CD and can be written to floppy in Windows using rawrite (in the folder /dosutils on the same medium).
Boot from these floppies and point to the ISO as installation source. I am not sure if you need to unpack it first (WinRAR is able to do so).
EDIT: again slow typing.

and how to boot from those live CD's iso images?
You cannot boot from software! You need to have a hardware device.
The only way that I am aware that you can "boot" from an ISO image without actually burning them to a CD and rebooting is to use M$ Vitural PC. But first, you need some sort of Virtual CD drive that will "mount" an ISO file and allow Windows to see it as a CD. I can't remember off the top of my head what I use (haven't booted to Windows in awhile, I think it's called something simple like Virutal CD). I've used the combonation of the two to try different LiveCD distro's before I repartitioned my HDD.
Make a bootable Knoppix Floppy, CD, Thumb-Drv, whatever. (yes everyone here is right. you can't boot directly from an .iso your going to need a bootable device).
Assuming you want to boot the "knoppix.iso" from your C:\ partician here is what you would enter at the knoppix prompt:
Boot: bootfrom=/dev/hda1/K*.iso
after booting the cd would no longer be needed, however, now /dev/hda1 is now going to be mounted as if it were the CD-Rom and will only be read-only.
