Windows Bootable problem at 8gb pen drive and iso file to Gif file problem solution

Windows Bootable problem at 8gb pen drive and iso file to Gif file problem solution:-

A Windows or operating software is about  4 GB in size. Its ISO file requires 8GB of space on the pen drive to boot.
 An 8GB pen drive has space of only 7.22 GB. That means there is no 8GB of space on the 8GB Pen drive,
so if you want to boot the ISO file from Windows with an 8GB Pen drive, then a pop-up box will show

and bootable will not be.
If you want to boot into any Windows ISO file pen drive, then you must use 16GB pen drive. Then the Windows ISO file will be easily bootable.
