How do I make bootable media which includes TestDisk?
I have TestDisk files ready to load onto a DVD and a USB stick; mostly for use on Windows 7 NTFS HDs.
How do I create a bootable DVD and a bootable USB stick that will have TestDisk ready to go to work?

First create a MS-DOS bootable pendrive with Rufus. https://rufus.akeo.ie/

(In "Create a bootable disk using" select MS-DOS from the dropdown arrow)

Download Dos/Win9x version of Test Disk TestDisk Download - CGSecurity

Extract the downloaded zip file. You will get a testdisk-7.0 folder in which you will see all the TestDisk files (exactly twelve). Select all files and copy those to the bootable MS-DOS pendrive you just created using Rufus.

Now boot from the USB pendrive. DOS will be loaded and you will see a C:> prompt. Type testdisk.exe and press enter to run TestDisk.

(Against the Command prompt type photorec.exe and press Enter to run PhotoRec.)

Thanks jumanji! Taking all of this home, can't do much "on the fly." :)
