I had the same D-Bus problem so I downloaded MiniTool Partition Wizard CD (it's up to v8 now), burned the ISO with Brasero, booted to it and watched it come up... in Linux. Made me smile.
Linux or not, it worked. Both the little fallback NTFS partitions I'd set aside just in case, are readable now. GParted team, take note - if MiniTool does that under Linux, GParted could too. Presumably. (But what do I know?)
Anyway, thanks for the only tip I came across that was both written in readable English and actually worked. Now I'm finally out of Windows. Gotta fix Grub and let VirtualBox or PlayOnLinux run any Windows program I need. POL even runs MS Word, Excel and PowerPoint right from the desktop, though I like Libre Office just as much.
And now I have accessible spare NTFS partitions sitting there empty but accessible. Made so by MiniTools running under Linux. Yup - still makes me smile.
The free ISO can be accessed by links at http://www.partitionwizard.com/partitio ... le-cd.html
if anyone else needs it.
