  • 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.

This sounds right. Because so many drives these days are NOT MBR, they're GPT, and DOS and SpinRite 6 couldn't handle a GPT partition. Rather than allowing the drive to cause issues preventing SpinRite from working with it at all, it's likely Steve just removed the support for "comprehending" the partitions. I suspect GPT support (if any) for SpinRite will be part of the 7.x series.

Naw, this is on my old XPS15z, the same one that millq6.exe trashed the dual boot sector of the c drive & usb thumb drive. They are definitely MBR. I distinctly remember under v6, both partitions were shown under drive 0, as Items 3 & 4 I think win 7 & win 10. In 6.1 all I see is one drive! In the attached shot, of another computer, you see it working on Item 7. Unfortunately my copy of 6 is at a friends house, on this very screen shot, so I cannot check, yes I know I could download a copy of 6 and check, but I am going to see him this week, so do not want to waste time making another cd.
Thanks for the input though.

I wasn't implying it would do MBR partitions. The implication was that Steve had removed ANY support for partitions because there are ones he can't yet support properly (GPT.) As mentioned above, this appears to be the situation... it's now whole drives.
