My laptop is an Asus N55 on windows 7 and encrypted with Truecrypt, I have been holding off upgrading to windows 10 because I'd read that I needed to unencrypt my system drive and back-up first, but it seems that Microsoft isn't quite so thorough. Like everyone else I have been getting the increasingly heavy handed invites to upgrade to windows 10 but on Sunday morning I started the laptop to find I had no OS to boot up and none of the recovery options work. I have managed to retrieve the 'WindowsUpdate' and 'ReportingEvents' log file and both seem to point to an attempted upgrade when I shut down on Saturday night.
The problem I now have, apart from the two wasted days trying to get to the bottom of this, is that I cannot find the Asus recovery media and I cannot download an original iso as my copy of windows was pre-installed, so currently I have nothing to re-install. Any suggestions on how I can get hold of a genuine copy of windows 7 to rescue my laptop?
