I have 16Gb Flash. I use Multiboot iso 188.8.131.52.2. when I select ISO files but not selcet. dont show. but I have ISo Files.
You mean the Pendrivelinux Multiboot OS tool?
Make sure you download the correct ISO files and install it according to the steps provided. Sometimes iso have a different name and you have to rename it to the ones that the tool requires.
Your problem reply is at best confusing and not a coherent response??
