Thanks Martin for the quick reply. So CCleaner is the "bad guy", actually it cleans Windows Log files (including setupact.log) by default and I didn't disable this checkbox. Anyway UEFI Boot seems to be fine, that's the good thing.
Thing is, I have CCleaner installed, and obviously it has deleted the setupact.log file in the \Panther directory. However I have one setupact.log file in the Panther\FastCleanup directory, don't know if this is helpful?
Hi,
i have installed Windows 8.1 in UEFI mode. Secure Boot is active, which indicates that UEFI Boot is working. ESP-Partition is OK. However HWINFO tells me that UEFI Boot is "not present". Is this a bug or what did i do wrong? Any help appreciated. Thanks.
