How to Create a Bootable ISO File

By Nina Nixon

Spanning unique operating systems including DOS, Mac and Windows platforms, the bootable ISO (International Organization for Standardization) file format is interoperable. By being flexible geographically, this file type provides a way for many industries to cross language barriers, all having equal access to maintaining high standards of quality in providing goods and services. Learn how to create a bootable ISO file for a more consistently reliable operating system environment, no matter where you are, whether at home or abroad.

Things You'll Need

  • Nero Burning ROM SE software

Step 1

Open Nero Burning Rom SE and go to the "ISO" tab when the New Compilation dialog box appears. (NOTE: If Nero Express 6 displays, click on the "Nero" button on the bottom-left side of the software program. Otherwise, select "File" and then "New" from the toolbar menu.)

Step 2

Select format "DVD-ROM (Boot)" from the New Compilation dialog box and then press "New." (NOTE: You have the option to select "CD-ROM" by selecting "CD" from the pull-down list at the top left of the New Compilation dialog box. Next, select "CD-Rom (Boot).")

Step 3

Make the following selections at the New Compilation dialog box. Select "ISO 9660 + Joliet" for the File System; "Max of 11 = 8 + 3 (chars) Level 1" for the File Name Length (ISO); and "ISO 9660 standard ISO CD-ROM" for the Character Set (ISO). (NOTE: The Character Set is the same for both DVD-ROM and CD-ROM.)

Step 4

Check the following boxes under Relax Restrictions: "Allow path depth for more than 8 directories," "Allow more than 255 characters in path," "Do not add the ",1" ISO file version extension" and "Allow more than 64 characters of Joliet names."

Step 5

Highlight your desired files and "Drag and Drop" them to the bootable section on the left. When finished, choose a recording device and then press the "Burning Compilation" icon. Next, press "Burn."

Step 6

Type a name for your disc at the "Save As" prompt.

Step 7

Press "OK" and then press "Done" at the end of the burning process.

Step 8

Choose to save your file and type in a name for it at the "Save As" prompt.

Tips & Warnings

  • Create a low byte size bootable ISO as a test file. Open it and ensure that the proper settings were applied, just as you wanted. If required, make adjustments and retest. Doing this now will save time in the long run.
