Hmm that's interesting. Are you having the exact same problem, with the restart happening at the same stage of the installation and with the same error message? What kind of things have you done with nLite? Do you have any suspicion what settings could cause this? Actually, could you post your nLite session .ini file, so that I can compare the similarities between our settings? By the way, are you installing on a laptop or a desktop? In any case I guess it's reasonable safe to conclude that since we are both bumping into this problem, it's something we've done in nLite, rather than a hardware/BIOS/whatever issue. However, since at least in my case the installation get's stuck so early (the actual installation just barely starting), I think most nLite settings shouldn't have an effect so early on... At least I'd assume that the component/service removals wouldn't have an effect so early on, do you agree with me? Similarly the tweaks and patches seem like something that are applied at the last stage of the installation... So maybe it's something in the 'unattended' -page?
