Absolutely, I already had http serving in-place so the additional 1GB size result was negligible impact. Thanks for the additional insight, however.
Happy to help out, I just noticed a majority of posts about this ended with users reporting Hiren over PXE was “solved” by simply updating their wimboot version, with no other notes. While it does fix booting it, it is only part of the solution. It’s necessary to do that but it is not a complete fix. You need the Y:\ mount fixed or else the booted ISO is still heavily broken. Hopefully this helps some people out. HBCD is a great Swiss Army knife.
