Hi, I followed the instructions exactly. At stage 4) there was indeed a little "system reserved" partition from our previous efforts (little unallocated space, little system reserved partiton, the rest of the unallocated space, the data partition). I deleted it so that I just had 150gb unallocated and then the data.
At stage 6)R I noticed the partition was marked primary but not active, unlike the system reserved partition which is primary and active. Is that correct? The partition size said free space before 0, free space after 28.66Gb. I tried changing it to 0, but that just made it say that there was 28.66Gb _before_ and 0 after. I put it back to the before setting, and proceeded.
At stage 6)S the 2nd volume label was blank, which I presume is correct.
I clicked proceed 6)T and after a minute or so got the "Recover operation failed" popup.
