BootAble – FreeDOS boot testing freeware
To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.
GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.
The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.
You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Respectfully disagree.
Level 5 writes all areas of the drive two times, first inverted and then back to normal. PLUS an initial write for any area with data recovery required.
I cannot see any advantage over a level 3/4 scan which does much less writing. Why needlessly stress solid state media (flash, SSD, NVMe) with no advantage to be achieved?
Correct! And it's a HDD. Level 5 is quite appropriate for that.
Level 5 was developed for spinning hard drives, long before solid state media came into being.
Spinning hard drive technology and solid state drive technology are two different things.
The fact that modern solid state media technology may be more tolerant of Level 5 stressing is not the point.
The point I am attempting to make is that level 5 provides no advantage over a level 3 or 4 scan for solid state media, in exchange for the extra stressing that level 5 does..
