It must be a solution which prepares the USB flash drive for simple UEFI boot and let me add (before or afterwards) an additional tool. I guess I have to declare (where?) what program should be started during USB flash drive boot. Surprisingly a DVD-bootable ISO is NOT automatically bootable from USB flash drive due to different handling of Bootmanager.Ĭan I convert this only-on-DVD-bootable ISO to a bootable-from-USB-flash-drive ISO?Īlternatively it would be acceptable to create at first an UEFI-bootable USB flash drive and extract (which?) tool files out of the ISO onto this USB flash drive. Yes, the file and the directory is missing.
"Could not locate 'EFI\boot\boot圆4.efi': Not found These days most PCs can boot from USB, so you need no DVD drive any more to install Windows 10. Rufus onto an USB flash drive then the USB flash drive does not boot and show an error message: Create UEFI Bootable USB Drive to Install Windows 7. If I burn this ISO onto a DVD and boot it on an UEFI computer (without Secure Boot) everything works.
I have an UEFI-based ISO file for a tool on windows (This tool is NOT a WinOS but a separate utility tool).
