How can i make a windows 7 bootable dvd.

I have tried to burn Windows 7 from drive d:\ to dvd - r. But, as I added the files to be burned, there was a prompt message that states that the file "install.wmi" can't be burned because its size is greater than 2GB. And it also suggested that I have to use a file system called UDF. Could somebody help me figure out the problem? Thanks a lot...

Does the file look like this?

Are you trying to burn the seaparate files to dvd?

Usually you make a bootable .iso in UDF format and burn that to dvd as an image.

You probably should have started a new thread for this, rather than appending your post to one that's two years old.

The normal way to make a bootable DVD is from an .iso file, which is a software image of a DVD. I use Nero to create the DVD from the .iso. There are other utilities that'll do that, including ImageBurn (free version).

As you mention install.wmi, you appear to have the installation files on a hard drive, rather than an .iso. I hope that the way those files got there didn't involve piracy, discussion of which is forbidden here.

Well, I just want to create a back up for my windows 7 installer. Ok, therefore, what i need is the .iso file of an installer when i am going to create a bootable dvd. Is this method applicable when creating a bootable dvd for operating system?

The best way to back up your Windows 7 installer is to extract the ISO with ImgBurn and back it up to your Downloads folder or Storage partition. If needed burn it to DVD using ImgBurn or write to flash stick using this tool with Windows 7 in dropdown menu: Universal USB Installer – Easy as 1 2 3

This is for your Win 7 installation DVD. Another method is to back up an image of your existing installation which can be reimaged to the HD or its replacement using the DVD/Repair CD and the stored image: Backup Complete Computer - Create an Image Backup

If you have factory preinstalled Windows 7, you should also make your Recovery Disk set so you can restore your computer to factory condition if ever needed. But this method includes all the preinstalled bloatware so is inferior to using a Windows 7 installer or your own image.

Ok then. I will try the method that you have suggested and I will give you a feedback if it really works. Thank you.

As Greg says backing up your installation DVDs should be that straightforward.
I back my 3rd party installation disks that way. The activation keys provide piracy protection.

You can mount the ISO with PowerISO to see if it runs from within Windows 7.
