The 'system repair disc' by that and similar names is a legacy technology that fell out of favor many years ago. It's replacement is the backup image, which is an exact copy of the hard drive (or a partition) that can be made in minutes.
When restored, which also takes minutes, the computer returns to exactly as it was when the image was made, with no need to recover, repair or reinstall anything.
There is an entire industry built around imaging, and many of these same developers now make consumer-friendly versions of their software.
Hi BullDogXX
The "System Repair Disc" is a small bootable 525MB utility program (on CD on DVD media, used for booting up (outside of Windows) an otherwise inoperable/unbootable computer. It boots you into a self-contained 'Recovery mode', and thereby allowing you to search for your previously saved System Image 'backup copy of your entire computer. It works well (It has saved my Windows 10 laptop a few times), and is the only means available for recovering/replacing your saved System Image if your computer is otherwise unbootable (ie the OS code is badly corrupted, or your Int. Hard Drive is being replaced
(with a blank), etc)
