Homebuilt desktop - Windows 7 64bit Ultimate, Asus Sabretooth Z77, Samsung EVO 850, 1TB, WD Blue 1TB, Seagate 1TB . Last time I used the machine it worked perfectly. Added the EVO about a year ago and used Acronis to clone the WD onto the EVO. Created a Macrium rescue disc and a Win 7 recovery disc. Re-imaged the WD to use for video editing an digitization for music. Cloned the Seagate from the EVO as it was the oldest drive and most likely to fail - just kept for emergency boot if necessary. Booted the machine from both drives (all others disconnected) and each came up fine. Been using it for a year like this with no problems. Had been turned off for two weeks due to travel.
First clue when I pushed the power button today - nothing happened. Unplugged the AC for 30 seconds, plugged it back in and boot sequence started but went right to setup screen (low CPU fan speed but it was about 65 degrees in the room). We did have a power loss for about 2 hours during that time period. Everything recognized, pressed F10, save and immediately received the prompt to repair windows. Macrium, Win 7 recovery, and original MS install disc all say recovery succeeded but after each boot, no OS found. Re-boot to command prompt with recovery disc and bootrec /scanos shows no OS. Same story with the Seagate.
Any tools for MBR malware detection available?
