Create a vitual CD/DVD drive. Convert the installation disc to an image, mount it on your virtual drive and proceed with the installation Do not install the software that creates a virtual drive like Alcohol or Ultr-ISO on any partition other than C where you are likely to install the OS.....
Otherwise use an external CD ROM and do the same by booting from the CD by altering the boot sequence in the BIOS!.......sodeep

If the earlier method did not work then get hold of an external CD ROM with a USB connector. Plug tthe USB jack, start your PC and keep hitting the DEL key to enter BIOS, go to boot options and the first option to boot from any removable drive( it can be memory stick like a pendrive where the entire contents of your OS CD has been copied from another PC) anjd whn prompted to hit any key to boot from CD, press any key and follow the instructions as they apear on the screen.....sodeep
