My first post here! I am testing Windows 10 on a separate disk. Last week I installed the latest build - 10041 if memory serves - and all was good.
I had a little trouble when I installed Virtualbox and the Virtualbox's USB drivers prevented my keyboard and mouse from working. I manually deleted all virtualbox's USB drives (from another OS) and Windows reinstalled the default ones.
Today I powered up my PC and after the sound card was initialised (I could hear the usual "click" over the speakers) the PC rebooted. Windows did not help, did not give any warnings or errors. Safe mode does not work either, PC reboots in the same place.
What is weird is that I enabled boot logging but I cannot find the file. I googled it and it should be under C:\windows\ntbtlog.txt but it's not there. I turned windows 10 HDD off as soon as the system rebooted - allowing Windows 7 to boot up, in case Windows 10 was deleting the log file during the following boot - but still the file is not there.
I'm a little stuck. I'd like to try and recover the system before I try to 'refresh' it.
Any help? I'm afraid I won't be able to give more information, I simply can't find any.
Thank you all for your help!
