Ah. thanks

No, not that specific one, but all the instructions are essentially the same.
The instructions I tried actually went into more detail and I followed these to the letter and still got the error message when I was done.
Then I read the error message can just be ignored, except the error message that was referred to was very similar but not identical to the one I got.

Save yourself some time and grief and just use Lion Diskmaker.
I have heard only positive things about it and it's a lot easier than the manual method plus no error messages at the end.

The error message doesn't matter - it works anyway. See the instructions on arstechnica

I've read arstechnica and a ton of other websites and discussions on that.

Yes, arstechnica claims one can ignore the error message, but as I mentioned earlier in this thread - the error message I got was slightly different than what they are talking about, same format and basic message but with a few different words, so I don't even know if what they claim applies in my case and on top of that, nobody has a clue why that error message appears in the first place - some people get it, others don't even so they supposedly all follow the same instructions.
Error messages usually don't appear for nothing (notice I said usually).
It's quite possible that the installation with the "error message" USB installer seems to work fine when one does the install but then unexplained problems happen later because some code is missing.

If there had been no other option than to do this manual install, I would have left it at that, but with Lion Diskmaker available and all the positive reviews about it, why take a chance?
It's also a lot easier and faster to use diskmaker - seemed like a non-brainer to use it.

It worked for me no errors. I followed this one above as it was more detailed.

Installing Mt. Lion now.
