I have a dual boot (Windows 8 and Windows 7) laptop. Based on the OS, I use Legacy BIOS or EFI. The Windows 7 is installed using EFI in GPT partition (I hope I am using the correct terms). I use Windows 7 more often and recently it got infested with viruses / malware. I use Avira AV, Comodo Firewall and Malwarebytes.
With a combination of these, I was able to remove all the viruses and I was using the laptop normally since a couple of days. But then the next day, I was getting the above error. Tried everything : Windows recovery, startup recovery, checkdisk, command prompt bcd rebuild, sfc scan etc. I am not able to boot in Safe Mode or anything like that.
Currently I am posting from the Windows 8 system.
I read that FRST may do the trick with a lot of help. Please advise.
