First step is to download a puppy linux ISO such as Precise Puppy.
You can now prepare a USB device such as a thumb drive on
a friend's computer if you're afraid of modifying your windows computer.
You MUST find a computer that is currently running Puppy linux.
According to documents which come with Boot flash written by Barry
Kauler, it is difficult to boot a PC with an ISO of Puppy. He says
that he was only able to get 2 out of 4 of his computers to boot.
So he recommends that Boot flash be used to prepare the
USB device ----> it does a reformatting to 2 fat partitions.
One partition holds the puppy and the other is empty for future use
(like exchanging documents with a Windows install).
The Boot flash application installs the required files
from an puppy ISO.
I used Precise Puppy or Wheezy Puppy to set up my USB device.
(in my example it was a USB SD card reader)
Start Menu > Setup > BootFlash install Puppy to USB
Now that the USB device is prepared you can use the Plop CD on a
Windows computer even if USB drive port is non-bootable.
I will now have a choice of where to find an operating system.
In theory a computer without a hard drive can be used.
Some people have reported this in the Murga forum.
Once you have an operating system booted you can then remove
the PLOP CD and the USB device so that your CD player is free for music
or stick another USB thumb drive in the port.
