A week ago borrowed Windows Operating system Dvd from my friend to install a new OS on my computer. And after installing it I also copied all the files of DVD to create a backup of it. So that I can also have one copy of my friend's DVD which I can use anytime to install. But after some days I realized that instead of copying files from that DVD I have to create a bootable iso file from it. And Now he also doesn't have the Dvd. So is there any way I can make a bootable iso from files copied from it.
Help me in solving this issue.

If the below screenshot matches what you see, you simply need to select the DVD-ROM (ISO) option in the sidebar on the left.
If the sidebar doesn't match what you see, I can't help you with Nero, as I don't use it. However, in that case you might try seeing the instructions at http://www.ubuntu.com/download/ubuntu/download. Click "Show me how" at Step 2 ("Burn your CD or create a bootable USB stick").
Ok after some research I've figured out a solution, and I'll go through it step by step. Problem was two-fold.
Plug in the USB flash drive and determine the device it's mounted on with the command:
sudo fdisk -lThis time around it was /dev/sdc1 for me, so I'll use that as my example.
Umount the device
umount /dev/sdc1Not sure if necessary but I formatted the drive in FAT32, just in case
sudo mkdosfs -n 'USB-Drive-Name' -I /dev/sdc -F 32Now my ISO was using isolinux not syslinux. I knew it worked with CDs so I figured out that I needed to call the isohybrid command, which allows for an ISO to be recognized by the BIOS from a hard drive.
isohybrid filename.isoYou can find out more about this command here, but this was the cause of the message "Missing Operating System" The first problem was fixed, but now it said "isolinux.bin was missing or corrupt"
The next step is to copy the iso. My second problem lay here, where I was copying to the partition, sdc1, not the device, sdc.
sudo dd if=filename.iso of=/dev/sdc bs=4kThis seems to work just fine, but the forum where I got the last fix, it was recommended to do the following before unplugging the device:
sync sudo eject /dev/sdc

I totally agree with you, downloading ISO from Microsoft and using a USB drive is a nice idea. And USB works really quickly as compared to DVDs. But what if the user wants to create bootable iso for Windows 7. In that case, you cannot download the iso from the Microsoft official website without the genuine product key.
And in that case, creating an ISO from Windows installation files would be a better option.
And Yes it depends on the user to user.
So if you want to create bootable iso from folder or files follow this guide:

That's it. By using these steps you can easily create an iso file & use it in USB.
Thanks.
