My laptop has got a virus and I cannot get it fixed no matter what I tried. I want to reinstall the operating system, but I don't know where my Operating System Disk is. Is there any other way to reinstall the system without the disk? I have the disk with all the pre-installed programs, I just need ti reinstall the system.

You eather need to find the disk or contact www.microsoft.com and have them send you a new one there is realy no other way to do this

hope this works for you

What is the brand of your computer? some branded computers have an image inside the hard drive which you just need to access like in some dell computers. try checking out the manufacturer. try also looking inside your hard hard drive or click my computer.. if there are more than 1 drive inside and you just have 1 hard drive installed chances are the other drive could be the factory image of your system which you can try to restore
for proper image restoration try to contact the manufacturer of your computer
