Hi Tannah,
thanks for the info.
Puzzling indeed, as stated earlier next time use the Remove Editions option on the Apply page to remove all of the other unused editions, that way it would be impossible to install the wrong one.
As there is no Enterprise to begin with, then there must be some kind of a recovery partition on that machine, depending how the setup was started.
Make sure to boot it in UEFI mode from the bios, and that the prompt to boot from the USB stick was seen counting, then press any key.
As a sidenote there also the .\Sources\ei.cfg which may influence it, remove it manually before editing the image, there is also a component for it "Edition configuration file (EI.cfg)" if you want the tool to do it - and if it's even present, doesn't have to be, but when it is, in it is also written what to install.
NTLite does autoedit that normally, but it's worth checking.
Regarding the post-setup, it can be that an installer half-way threw an error or a prompt then the rest got skipped.
To debug that see
here.
And the reg files, please use Integrate - Registry page for those, not Post-setup unless they require reapplying after.
And when using integrate - reg, if it still doesn't apply half of it, add those to the post-setup page for reapplying.
Sometimes user settings (HKCU) get reset on creating the profile after setup, so it's expected and not even post-setup reapply helps there.
But we can check that in more detail once you have a reliable setup.
Thanks.
