But before we begin. let’s know more about prerequisites.

However, creating ISO from a bootable USB is pretty easy but you have to follow the exact steps with the correct settings. Two settings in which the majority of users get confused or enter wrongly are the Boot Image file and Sectors To Load.

And to help you out with this, here are the right settings.

• Windows 11 = Sectors To Load: 8 and Boot Image: E:\boot\etfsboot.com
• Windows 10 = Sectors To Load: 8 and Boot Image: E:\boot\etfsboot.com
• Windows 7 = Sectors To Load: 8 and Boot Image: E:\BOOT\ETFSBOOT.COM

Note:- The drive letter may differ in your case. So, select carefully.
