The ' www.ventoy.net' string baked into BOOTX64.EFI is NOT a URL
- it's a magic GUID (16 bytes: 0x77772020 0x2e77 0x6576 ...) that
spells ' www.ventoy.net' when interpreted as ASCII. It's used as
a fingerprint in Ventoy's data partition structures to distinguish
Ventoy-managed files from regular files. Changing it would break
disk format compatibility.
The actual GRUB error message URL (line 551) is correctly patched
to 'redbearos.org/hiperiso to use Hiperiso'.
Build script also copies chain-boot EFI binaries (hiperiso_x64.efi,
iso9660_x64.efi, udf_x64.efi, vtoyutil_x64.efi, wimboot.x86_64.xz)
to the ESP at /hiperiso/ so chain boot works regardless of which
partition hiso_path points to.
