only if you teach them how to boot from USB.Perhaps a USB key could work for Vista/seven users
That is different for each machine. Some need one go into BIOS and change order. Some machines allow one du F12 and there chose the USB
and all this has to be done within some 5 seconds or so at boot up?
Nope not everybody manage to do such.
I tried to boot from USB with several Puppy and other Linux on my Acer very modern only some month old Net top computer.
Some times it was impossible to boot. And I spent many hours on how to do it and it was very difficult. One the HP/Compaq it works almost each time same USB.
So it is highly individual if it works.
So I support one do find easy ways to let people get to know Puppy linux.
DVD does not always work either.
the Acer is too small to have a DVD one need an external such and not everybody care to buy such.
and DVD not always work to boot. I failed with two different Linux distros on my neighbors computer. I was helping him with getting antivirus before him activated his new windows XP installation.
Puppy on DVD would be ideal for such download. But it failed to boot.
