Hi Shiw...
I see. The first thing that we need to determine is if you have a restore partition on your hard drive. If you double click on "My computer," do you see two different drive letters (on the hard drive,) C and D?
If "C" is the only one listed (with D as your CD-ROM,) then you will need to contact Microsoft at (800) 936-5700 to discuss the situation with them. You will probably need to dial additional numbers from Mauritius where you live.
God bless
