hello from IQBAL guys some times we need to install windows but we don not have CD-ROM in our laptop to insert the disc or our CD-ROM is out of work. we need not to worry about this as we have an alternate way of installing windows. GO THROUGH THE FOLLOWING STEPS: 1) first we  need to find .iso file of the windows we want to install. if you have a window disc, you can get .iso file from it using BURN AWARE  Software tool. or you can search the .iso file on internet and download it. 2) we need to create a bootable usb using POWER ISO software. 3) enter BIOS set up  of the laptop, goto Boot Order and Select USB first. 4)now insert the USB into your laptop and restart it. it will prompt you to "press any key to  boot..." 5) go ahead and install the windows as you do... good luck. if you still need further guidance , feel free to ask in comments.
