Can anybody here tell me how I can make a bootable ISO file from folder or files copied from my windows 7 genuine DVD? Due to lots of scratches on it, it's not working properly and I am only left with copied files of windows 7 DVD on my PC. I can still install windows from it but it will create problems while booting the PC. Please help ASAP. Thanks in Advance.
