Sorry to say but I am almost convinced that the technician is wrong. I took you through chkdsk /r because it's the simplest, least risky command. It helps in lots of cases but certainly not always. There are other commands that we could lead you through but these also are not always successful and can end with serious problems and even loss of data. Among them are bootini /rebuild, fixmbr, fixboot and Windows Repair installation.
Backing up the data from a laptop can be somewhat more complicated then from a desktop. Judging the situation in which you are, a computer that is still under guarantee, I think that your best option is to take the computer for data backup and repair to an authorized lab. However, if you wish to backup the data yourself please let us know and we will guide you how to do that.
