After the auto-reboot it again fails to update to v1803 giving the codes for failing at the safe boot stage due to the drivers and reverts the system back to the clean v1709. We'll restart for you'В and 'Stop Code IRQL NOT LESS OR EQUAL'.

The v1803 starts installing and goes through a few of the early steps eventually producing the now familiar message 'Your PC ran into a problem and needs to restart. Device Manager confirmed that all drivers were correct. I even didn't connect to the internet in case updates started to download automatically. The clean v1709 installed successfully from the DVD and I left it in bare bones state except for UK language, keyboard and time zone. Do I need to download it from a link from you or can I make a bootable DVD rescue disk from the nw8240? I guess a bootableВ v1709 will at least confirm that W10 can boot from DVD. I'm happy to create and try v1709 from a DVD but that is the version which is currently installed, so won't that be rejected as already present? The v1709 is the last major update which installed successfully, v1803 onwards have been failing since May 2018. It did the same when I tried it again and opted for not keeping anything, it still re-booted into v1709 with all my files and apps completely intact.

It apparently went through the whole install process for a couple of hours (giving options to keep or not keep personal files and apps) and then after the final auto-reboot it booted to the original v1709. Incidentally, I don't know if this gives any additionalВ clues but the first time I tried installing v1803 I mistakenly did so by running the setup.exe file as an administrator from the DVD. I've just tried it and it boots up the nw8240 into W7 faultlessly so I'm guessing it's something in the v1803 that doesn't like the nw8240. I suspect the problem is hardware/config related rather than the DVD because the DVD works fine on other HP PCs, but as it happens I do still have a Win7 bootable rescue disk which I created specifically for this nw8240 laptop prior to the migration to W10. Thanks for an amazingly quick reply and the additional tips:-)
