Yes, I did do that, but that was when I was also loaded into the windows 10 OS. I suppose they mean shut down the laptop, boot to BIOS, and from there boot into the Windows 7 DVD instead of Windows 10. Then install Windows 7 as per the guide linked in the second post.
If that gives me the 0x6 error as well... then you're right, the best move would be to use the Partition Wizard to delete all of the partitions (with the exception of C, as the OS would already be loaded in C), install Windows 7 from the free space created, then get rid of C and install Windows 10 from scratch, dual booting with 7. That way I'd just have C (Windows 10), D (Windows 7) and E (DVD drive), along with a windows 10 bootable USB (that I bought with the laptop) and a bootable windows 7 disk. With the bootable disk and USB, there wouldn't be a need for the current D drive (Recovery) - so that space could then be used between 7 and 10.
