Problem.
I don't have that CD :X
Option 1 :
- Find the CD with same windows version with your current. Can be buy or bought from friend.
Option 2:
- Bring your HDD and connect to another PC with same windows version and copy the system dir from that PC to your HDD and try booting the PC using your HDD as primary boot device.
Option 3:
- Go to technician with your PC/call technician if available.
Hope this will fix your problem.
