Hello everyone,

I got a weird problem.
Just started installing Win8.1 from the USB to my Vaio VGT-TT. The installation went well till the first restart, after that the system just gives me "Operating System Not Found" message.

Any clues on how to fix it?

Try to go to BIOS and click on the drive with OS. If it boots, it means installation is ok, you need to select boot preferences. If it does not boot, you may consider to run installation again AFTER you format the drive (assuming that it is clean install and you not trying to preserve any old files).
