Windows 10 2015 LTSB doesn't work. I already unremove Networking, system, services etc... and so on components since last night. I tried everything to isolate the issue but I'm still getting INACCESSIBLE_BOOT_DEVICE everytime the first install and reboot finished.
regarding the original report at the top, the error 2338 when integrating.
I saw similar on 1607 when Microsoft messed up the cumulative updates integration.
Make sure the servicing stack(s) and cumulative update pre-requisites are all accounted for and on the updates list.
Removals do not matter if not done in the previous session on the same image.
Note that I do not support updating Windows build 10240, so there is no ready update list or experience with it.
I suggest switching to a newer Windows build, why use such an old one in the first place if I may ask?
