How to Make Bootable DVD for Windows 10,8.1

Sometimes you want to install the operating system from DVD. Then you need a DVD which is bootable. The difference between a normal and a bootable  DVD is ,"A botable CD has files on it so that the computer can be ran from the cd, It has exe files on it to allow you to work with the computer when their is a problem with the hard drive. A non bootable cd can be one that has not been prepared by the computer to recieve files on it (formatting it) or read it. There are other disks that are not bootable but are used for backing up files, these disks require a operating system and some type of program to run the programs on it."

How to Make Bootable DVD Windows 10,8.1:

There are many softwares that can make a disk bootable. But here we use "ImgBurn" software. Download ImgBurn . Open it. You need to have a CD/DVD writer for your system.,An empty disk and the software that is described above. Right, let's begin!

•  Load ImgBurn!
  
• Click the 'Write files/folders to disc' button.Note: This is basically the same as switching the 'Mode' to 'Build' and setting 'Output' to 'Device'.
• Insert a blank (or erasable) DVD disc in your burner.Note: The message in the status bar should now say something along the lines of 'Ready'.
• Add the installation source folder to the 'Source' box.
• Switch to the 'Advanced' tab, and then to the 'Bootable Disc' one.
• Enable the 'Make Image Bootable' option.
• Set the 'Emulation Type' to 'None (Custom)'.
• Point the 'Boot Image' to the 'etfsboot.com' file within the 'boot' folder in your source folder - i.e. "T:\VISTA_INSTALL\boot\etfsboot.com"(In case you should change the directory by clicking on the search folder icon below the '+' Symbol which is exactly in the middle of the screen.
• Set the Emulation type to NONE(Custom).
• Enter 'Microsoft' in the 'Developer ID' field.(It can be either your name too but it is better to have Microsoft to reduce any errors in the future) .
• Enter '07C0' in the 'Load Segment' field.
• Enter '4' in the 'Sectors To Load' field if your etfsboot.com file is 2K in size (upto windows 7), enter '8' if it's 4K(for windows 8).
• Now we're ready to burn so click the big 'Build' button!
• Assuming your source folder is in order (i.e. it contains a 'sources' folder with an 'install.wim' file in it) and depending on your current settings, the program will prompt to correct certain things so they match (as closely as possible) an official Microsoft disc/image.
• Click 'Yes' to whatever it says needs correcting - these settings have been tried and tested so we know they work!
• When prompted, give the disc a name and click the 'Yes' button.
• You'll then be presented with one final 'information' screen before the program starts to burn the disc.

Double check everything looks roughly as it does below and then click 'OK'.
