When you are new to problems like this, it can be quite daunting. May I suggest that you download the Paragon Drive Backup 10 Trial from
http://www.paragon-software.com.
Install it onto a working PC and Create a bootable CD/DVD that will give yoou accesss to the drive. You can build the CD quite easily from the "Recovery Media Builder" located in the Tools Menu.
Once the system is booted with the CD, you will have the tools available to you to repair the MBR, Boot.ini etc. I found it quite useful.
